Furniture has always been made from individual elements, which are then assembled in a certain sequence. Previously, furniture screeding was carried out using locking joints, tenons and wedges, however, for simple objects The furnishings of the home were enough. Similar connections They are still used today in the manufacture of antique-style furniture. In modern furniture production fasteners are represented by a wide range of elements. This allows us to produce furniture of various shapes with in complex ways connections.

When assembling a furniture product, the location of the connected parts of the structure must be checked so that its integrity is not compromised during operation. This is what a furniture tie is intended for - a fastener that makes it possible to tightly and firmly connect structural elements, located in a certain position (most often at right angles) relative to each other. If previously furniture was assembled mainly using screws and self-tapping screws, now different types of ties are used for this.

This replacement is due to three reasons:

1. Increasing the aesthetics of furniture, thanks to the use of ties, the fastening of parts becomes invisible;
2. Each disassembly of furniture assembled with screws reduces reliability;
3. Sometimes the use of conventional fasteners is simply impossible for structural reasons.

And finally, the use of furniture ties allows for quick and durable assembly of the product.

Types of furniture screed

Depending on the purpose of connecting parts, different types of furniture ties are used. They differ in external design and the material from which the fasteners are made.

Confirmat

Simple and convenient use has made confirmat (or euroscrew) the most common type of fastener. This euro-screed consists of one element - a euro-screw, which can be called a reinforced version of the self-tapping screw. Its shaft is slightly thicker, has a blunt end and a massive, widely protruding thread. Thanks to the notches on its lower turns, the Euroscrew, when tightened, cuts a chamfer in the finished hole. This makes it come into even closer contact with the material being fastened.

The confirmat can be used to connect two furniture panels located at right angles. To do this, holes are simultaneously drilled on both panels: for the countersunk head and for the screw thread. It is better to drill them with a special drill for confirmat furniture screed. The countersunk head has hexagon slots.

It is not recommended to screw in confirmations with a Phillips screwdriver, since it is impossible for it to screw them all the way. If holes are pre-drilled in all parts of the furniture structure with a special drill for furniture screed, the furniture can be assembled with a confirmat faster than with any other type of fastener.

When connecting L-shaped or T-shaped furniture elements, eccentric couplers are used. This fastener consists of three parts:

1. A rod having a head;
2. A special clamp called an eccentric;
3. Stubs creating decorative effect.

The advantages of such tightening include the secrecy of the fastener (the hole is not drilled into front side furniture) and the possibility of its repeated use without the risk of damage to structural elements. Due to the complex drilling, which requires a furniture tie drill to drill blind holes, eccentric fasteners are often performed in the factory. For the eccentrics you need to drill holes with a flat bottom; this is easier to do with a Forstner drill.

Intersectional screed

Intersectional furniture screed is necessary for tightening individual sections, for example, cabinets in the kitchen, into a single block. Given threaded connection complete with screw and bushing. A through hole is drilled in the side walls of evenly aligned cabinets, a bushing is inserted into it on one side, and a screw is screwed into it on the other. Although both heads of the Phillips screwdriver are notched, it is the connecting screw that must be tightened, not the bushing. The notches on the sleeve are made to hold it so that it does not rotate in the part. You can tighten a pair of cabinets using 2 - 4 intersectional fasteners, which are best placed closer to the corners. Depending on the wall thickness, fasteners of different sizes are used.

Corner screed

Corner ties have been used in furniture production for quite a long time. This connection is made up of five elements:

1. A corner in the form of a metal plate bent in the middle at a right angle;
2. Pairs of bolts;
3. Two footwear.

To connect two panels with a corner tie, a corner is placed at the point where they meet. Then the fittings are inserted and the bolts are screwed in, first to one panel, and after trimming the connection, to the second. In its finished form, judging by the photo, such fixation can hardly be considered aesthetic. 'Cause today corner fastener if possible, replace them with other furniture ties, for example, minifix or confirmat. Their dimensions are much more compact than a metal corner plate.

Screw coupler

Furniture screw fasteners are used when the end of one part needs to be attached to the surface of another. This fastener has only two elements: a screw and a barrel. A threaded hole is made in the side of a cylindrical metal barrel. In some screw ties, the barrel is made of plastic, then a nut is placed inside it. When installing this fastener, a couple of holes are drilled on the surface and at the end of the panel. A barrel is inserted into the first one so that the holes on the barrel and the end are aligned. The screw is threaded into a through hole drilled in the surface of another panel. The large tightening stroke makes the fastening particularly durable. The aesthetic error of this type of screed is considered to be the visibility of the screw head on the front side of the panel.

Conical coupler

The conical tie is an improved version of screw fastening. To hide the screw head on the front side of the panel in the conical connection, the screw was replaced with a rod. Unlike a screw that goes through the panel, the rod only screws into it. This reduces the tightening stroke and makes the fastener less durable.

Table top screed

During production kitchen furniture screed is applied furniture table. When the tabletop is assembled from two parts, paired fasteners are installed. Why use a Forstner drill to mill one hole in each part of the tabletop. A groove is cut between the holes using a chisel. Clamps are placed in it. A tension head with a C-shaped washer is placed in one blind hole. Then, using a wrench, begin to tighten the C-shaped nuts.

Furniture dowel

The simplest type of fastening is a dowel. This connecting element looks like a short piece of pencil made from a piece of wood. Today, when assembling furniture, the dowel complements the eccentric tie to give it greater rigidity, and it is rarely used as an independent connecting element.

How to choose the right screed

Choosing a suitable furniture screed has great importance when assembling furniture. The final result in the form of a finished product depends on it. There are quite a few types of screeds, so each case requires an appropriate approach to assembly. The selected type of fastener should not interfere with the operation of the furniture or spoil its appearance. To ensure these conditions, it is necessary to choose the right furniture screed and not violate the assembly technology.

Cabinet furniture pieces are mainly designed to store various things. Therefore, when assembling them, it is necessary to ensure the strength of the connections. Confirmat screed is best suited for this. This fastener allows you to connect parts at the desired angle. And thanks to the holes for Euroscrews, drilled using a special drill for furniture screed, Confirmat ensures high-quality assembly of cabinet furniture. The main disadvantage of confirmations is the unaesthetic appearance of the hats, which, although they remain flush, are still very noticeable.

An eccentric tie is another type of fastener used in assembling cabinet furniture. It is used where it is necessary to hide fasteners, for example, on the facade of furniture. The main advantage of eccentric fasteners is hidden installation.

Its high load bearing capacity due to design. Cabinet furniture is a prefabricated structure consisting of several pieces of furniture connected to each other. This necessitates the use of an intersectional tie, which is designed to tighten adjacent pieces of furniture.

The main purpose upholstered furniture- comfortable stay. Therefore, it should be comfortable, practical and last long enough. Fastening of upholstered furniture with a carriage screed must be reliable and have an aesthetic appearance. Ideally it should be invisible. All these requirements are met by a furniture bolt with an eternal companion, a nut. With such metal fasteners, the furniture will withstand the mechanical loads exerted on it during operation. In addition, the semicircular head of the bolt, which protrudes slightly above the surface of the parts, will be completely invisible under the upholstery, especially if there is a carriage tie on it.

Fasteners are an essential link in the furniture assembly process. They represent a wide range of fittings that ensure reliable arrangement of a set or individual furniture objects. Along with ordinary bolts and self-tapping screws, this class of fasteners includes ties. They often have a non-standard shape, and in some cases they are even developed specifically for specific sizes. But for the most part, furniture ties are produced in standardized configurations with standard fastening methods. Another thing is that there are quite a lot of varieties, and in each case an appropriate approach to installation is required.

Eccentric coupler

This element is used for fixing cabinet parts and intermediate modular shelving that require reliable fastening. The eccentric coupler contains three elements - a rod, the eccentric itself and a plug, which creates a decorative effect. Also, eccentric furniture ties are available in reinforced versions designed for structures with increased loads. The main function of such a screed is to ensure a tight and reliable connection of furniture components, and under different angles- from 90 to 180 degrees. The advantages of this method of tightening are that it is completely hidden from view and can be used repeatedly without the risk of damaging the furniture structure.

Installing an eccentric coupler

For high-quality fastening you need to create three holes with different diameters. The main task of the master is to ensure that the rod head is captured by the eccentric. To embed a rod into a sheet Chipboard drill a hole with a diameter of 5 mm is created. If this is the side, then the center of the part will be located 8 mm from the edge. On the other side, markings are created for two holes, onto which the eccentric furniture coupler will completely fit. The first fastener should be installed 3.4 cm from the edge. According to the standards, its depth must correspond to the diameter of the eccentric so that it sits flush. The second hole must be made with a 7 mm drill strictly in the center at the end. Then a rod is installed in the 5 mm hole, the second element is fixed on it, after which the entire structure is clamped tightly.

Intersectional screed

To connect parts of furniture for executive premises, an intersectional furniture tie is used, which also allows you to form monolithic structures. For example, with the help of this element you can combine into a single object sets for rest rooms and reception areas, reception desks, sets for workplaces, meeting rooms, etc.

As a rule, such elements are used to work with modular designs and sections, the fastening of which requires durable and reliable fittings. By design, the furniture intersection coupler is a screw that is connected to a plastic or metal plug in the hole. Depending on the parameters of the furniture, products of different sizes can be used. Since ties of this type work with individual models, and not with parts of furniture, they are subject to special requirements in terms of decorativeness.

Installation of intersection screed

First of all, holes are drilled through in the places where it is planned to connect the modules. This is an important stage, since during the process of through drilling of laminated chipboards, chips may appear. There are two ways to eliminate the possibility of their formation:

• A wooden block is pressed as tightly as possible to the drill exit points;
• Do several approaches. First drill a hole using a thin drill, and then bring it to the desired diameter with a tip of the appropriate size.

If the creation of the hole was successful and without defects, then the furniture screed is installed, followed by the furniture objects being brought together. It is advisable to prepare the furniture in advance for final installation at the assembly site.

Corner screed

This is a simple element in design, consisting of a metal plate bent at a right angle. The tie also has a hole and a groove on opposite sides. The complete set contains 5 parts: an angle, two bolts and two fittings. The advantages of such fasteners include the possibility hidden installation and strength. For small loads, a corner furniture tie made of plastic is used. Such models are distinguished by their aesthetics, but it is important to carefully calculate the fastening force so that later installation does not result in operational problems. All types of corner fasteners also include a problem with the arrangement of objects - bent plates in a furniture niche still conceal a small space.

Installation of corner screed

Installation is simple and does not impose any special requirements on the location of the filler holes. The product is applied to the future installation site, after which the drilling locations are marked. Depending on the material, the fixing elements can be screwed on without first creating holes. As a rule, furniture ties of this type are installed with screws measuring 0.4x1.6 cm. First, the part is screwed to one side, and after checking the ties for evenness, you can proceed to the other.

Usually two elements are used, which are mounted on the same level. Therefore, it is very important to ensure not only consistency in the fastening of two furniture elements with one tie, but also the proportionality of the structure as a whole - all used parts are responsible for this. In its finished form, such a fixation is unlikely to seem aesthetically pleasing, but to increase the decorative effect at the fastening points, you can use special plugs, which are supplied with a furniture screed. Photos of decorative corners, which also increase the aesthetics of the fastening, are presented below.

Conclusion

The use of ties for arranging furniture sets is profitable solution, due to them, the reliability and durability of the environment increases. In addition, using various models of fittings, you can implement the most unusual designs. Furniture manufacturers last years sets with unified elements are increasingly being released, which allows users to create non-standard and even unique variations of sets. In turn, furniture ties are distinguished by a variety of configurations and standard sizes, allowing for a non-standard approach to the design of commercial, residential and public premises. At the same time, their main functions remain just as significant - this is a guarantee of reliability, safety and decorativeness of the fastenings being sold. However, the extent to which it will be possible to achieve optimal quality in the assembly and installation of furniture depends on the quality of the installation itself and the correct use of a particular screed.

Furniture screed used only in furniture production. When making furniture, you should not use traditional fasteners instead of furniture ties, because it has special properties that not only facilitate the assembly of furniture, but also allow you to hide the fasteners. Next, we will consider the most commonly used types of furniture screeds and their features.

The most common type of fastener is confirmat. At the same time the easiest to use. With its help, assembling furniture is easier and faster than using other types of furniture screed. Especially if during assembly you have to drill holes for fasteners yourself. Using a confirmat, two parts are connected at an angle of 90 degrees.

Increase
Fig.1. Confirmat - used to connect parts at an angle of 90 degrees. The two parts are connected with 2 confirmed screws. The confirmat is installed at a distance of 3-7 cm from the end of the parts to be connected. To install 1 confirmation screw, you must first drill 2 holes in the parts to be joined: in the end of the first part for threads (drill diameter 5 mm), in the second part for the head (drill diameter 6 mm).

In order to tighten the two parts, you need to drill two holes. One in one part, with a diameter equal to the diameter of the confirmator head, the other, at the end of the second part, with a smaller diameter equal to the diameter of the threaded part.

As a rule, drills with a diameter of 6 and 5 mm are used for this, respectively. However, there is a combination drill available for drilling holes at the same time. It is very comfortable. There is no need to constantly rearrange drill bits or use two drills at the same time.

Increase
Fig.2. Drill for confirmation. Allows you to make a hole for 1 confirmat screw in two parts at once, and also forms a recess for the confirmat head. Increases the speed of furniture assembly by at least 50%.

Confirmat is a universal fastener, but it has some disadvantages and application features.

Confirmat should be used simultaneously with the use of dowels. A dowel is a wooden rod with a diameter of 6-8 mm and a length of 20-30 mm (in the photo below, next to the confirmation). The dowel acts as a guide and does not allow parts to move during tightening.

Increase
Fig.3. Connecting the parts using a dowel with a diameter of 6-8 mm and a confirmat. This joining method is used in factory furniture, for example furniture from IKEA. Provides high accuracy of joining parts.

Despite the fact that furniture assembled using confiramate can be assembled or disassembled, furniture made from laminated chipboard does not tolerate this very well. As a rule, after one disassembly, the furniture screed no longer holds well.

The confirmation should be wrapped carefully. Most best option manually or with a screwdriver at low speed. Otherwise, the confirmation thread turns into a drill, which breaks the hole.

Increase
Fig.4. Tightening of parts with confirmation. The tie is performed with a hand wrench or a screwdriver with a low rotation speed of the chuck. The screwdriver must have the correct tightening torque to prevent thread stripping.

In order to recess the head into the body of the furniture part, you should use a wrench and do it carefully, otherwise there is a possibility of the thread breaking. Sometimes it is necessary to pre-calculate.

Confirmat refers to “visible” fasteners. Those. Unlike other types of fasteners, it remains visible, so it is necessary to use special plugs or stickers to hide the fasteners.

Increase Fig.5. Plastic plugs (linings). Used to hide the confirmat's cap. They are attached to the confirmation cap in the key groove and are held in place by a specially shaped core. Available in various colors.

Increase Fig.6. Self-adhesive overlays for confirmat. Designed to hide the cap. Have a wide color scheme, completely identical to laminated chipboard panels. Almost invisible on furniture.

Eccentric coupler

An eccentric coupler is often used in the factory production of furniture. The reason for this is the difficulty of drilling holes. An eccentric coupler consists of two parts: a pin and an eccentric. The pin is installed in one part, and the eccentric in another.

Increase
Fig.7. An eccentric coupler is used to conceal the connection of two parts at an angle of 90 degrees. To connect 2 parts you need 2 eccentric couplers. The eccentric coupler is installed at a distance of 5 cm from the end of the parts to be connected. To install the eccentric coupler, you need to drill several holes according to the diagram. Instead of a rod with a length of 34, a rod with a length of 26 mm (shortened) can be used, while the remaining dimensions remain unchanged.

The main advantage of this type of fastener is that this fastener is hidden and therefore does not spoil the appearance of the furniture. In addition, this type of fastener, unlike confirmat, allows you to repeatedly assemble and disassemble furniture, which is important, for example, when moving. Also, using an eccentric coupler, you can connect parts at different angles.

At self-production furniture is not used often due to the difficulty of drilling holes and the inability to correct the joint during assembly. The main difficulty in drilling holes lies in the hole for the eccentric. This hole is not through and requires the use of a special drill - a Forstner drill.

Increase

Increase
Fig.9. Hole for eccentric. First, mark the part according to the diagram given above. Next, use a Forstner drill to make a hole for the eccentric. Then, using a drill with a diameter of 8 mm, a hole is drilled in the end of the part for the rod.

Increase
Fig. 10. Scheme of connecting parts using an eccentric coupler. First, the rod is installed in one part and the eccentric in another. Then the parts are connected and fixed by turning the eccentric clockwise through an angle of 180 degrees.

In this case, the sampling depth is about 12 mm, and the thickness of the chipboard is 16 mm. The remaining wall thickness is only 4 mm. There is a risk of drilling more than necessary, thereby damaging the piece of furniture. Therefore, when drilling holes for an eccentric tie, it is necessary to use drilling depth limiters.

Increase

Intersectional screed

This tie is a screw and nut with which two sections of furniture are pulled together, for example, two cabinets. To tie cabinets together, 2 to 4 sectional ties are used. Depending on the thickness of the chipboard, there are intersection screeds of various sizes.

Increase
Fig. 12. Intersectional screed is designed to connect cabinets (sections) of furniture to each other. To tie 2 cabinets you need 3-4 intersection ties. The intersectional screed is installed near the corners (at a distance of 3-5 cm from the end) of the sections being connected.

Considering that the intersection screed is used to tie cabinets, and the cabinets, in turn, are made of laminated chipboard with a thickness of 16 mm, an intersection screed with a length of 32 mm is most often used. However, there are ties up to 50 mm long, which are used to tighten parts of greater thickness.

Increase
Fig. 13. Screeding cabinets with an intersectional screed. To install the screed, you need to secure the cabinets using clamps. Next, make a hole with a diameter of 9 mm (1 mm larger than the diameter of the tie). Then install and secure the screed.

Shelf supports

There are a huge number of types of shelf supports. However, they can be divided into two groups: shelf holders for chipboards and shelf holders for glass. In turn, each of these groups can be divided into two types: shelf holders with and without fixation.

The shelf holder for chipboard consists of 2 parts: a rod and a shelf holder.

Increase
Fig. 14. The shelf holder for laminated chipboard is designed for reliable fastening of shelves in the closet. Available in two types, with and without fixation. Fixation is ensured by an eccentric. The shelf holder is installed in the shelf, the rod in the cabinet wall. To attach 1 shelf you need 4 shelf supports.

The screw is installed in the cabinet wall, and the shelf holder is installed in the body of the shelf. To install the shelf holder, you need to drill holes in the shelf and cabinet wall. For most shelf supports, the hole sizes are standardized; they are shown in the figure below. However, when installing the shelf support, you should carefully read the instructions to avoid errors.

Increase
Fig. 15. Hole pattern for shelf holders for chipboard. A hole is made in the shelf with a Forstner drill for installing the holder. There is a hole in the wall for the rod using a wood drill. The shelf holders are located at a distance of 5 cm from the front and rear ends of the shelf.

It should be noted that shelf holders for chipboard come with or without fixation. The shelf holder with fixation has an eccentric mechanism, thanks to which the shelf will be firmly connected to the cabinet wall. Shelf supports with fixation have one more advantage; shelf supports of this type serve as additional reinforcement of the furniture structure.

Increase
Fig. 16. Shelf holder for chipboard with fixation. Analogue of an eccentric coupler. Additionally strengthens the structure of the furniture and increases the rigidity of the cabinet. The shelf holder provides the ability to remove and rearrange the shelf many times without damaging the furniture.

Glass shelf holders have more simple design. They are attached only to the cabinet walls using a self-tapping screw.

Increase
Fig. 17. Shelf holder for glass. To install 1 glass shelf you need 4 shelf holders. The shelf holders are secured with self-tapping screws 16 mm long to the cabinet walls at a distance of 5 cm from the front and rear ends of the cabinet.

Shelf holders for glass without fixation are a rod or an angle. Shelf holders with fixation have a special screw with which the glass is firmly fixed and cannot accidentally fall out.

Increase
Fig. 18. Shelf holder for glass. The glass is fixed using a screw with bottom side shelf holder.

Table top screed

A special type of screed is required to connect two parts of a tabletop. Used in the manufacture of kitchen furniture.

Increase
Fig. 19. Screed for table tops. Provides reliable connection two pieces of countertops. To increase the accuracy of joining parts, it is advisable to use it together with a dowel. For a standard screed, non-through holes with a diameter of 35 mm and a depth of 19 mm are made in the connected parts of the tabletops. The distance between the holes should be 15 mm less than the length of the tie. The groove width must be at least 7 mm.

To tie two tabletops together, use a pair of ties. To install the tie rods, it is necessary to make recesses for the tie rod stops and a slot for the screw. This can be done different ways. The most affordable option is the following. The recess for the stops is made with a Forstner drill of a suitable diameter; the slot for the screw can be made using a jigsaw.

Increase
Fig.20. Connecting table tops with a screed. At least 2 ties are installed for connection. To install the screed, holes and a groove are milled in the tabletop slab. The holes can be made with a Forstner drill, the groove can be cut out with a chisel, or using hand router.

Furniture corner

This type of fastener is used to connect two parts. This is a rather fragile connection method, so it is used to fasten parts that are not expected to be affected by heavy loads. Usually these are decorative elements, for example, the base of a wardrobe or mezzanine shelves.

Increase Fig.21. The furniture corner is used for fastening decorative furniture elements (plinth) and installing shelves. Made from plastic. It has a cover to hide the fasteners. Self-tapping screws 16 mm long are used as fasteners.

Often used plastic corners instead of metal ones. They are no less durable, but have a more attractive appearance and the possibility of hidden fasteners. The furniture corner is attached to two mating parts using two self-tapping screws. Then the lid is snapped on, thus hiding the fasteners.

Increase
Fig.22. A furniture corner is used for fastening low-load furniture elements, including for installing decorative elements such as a plinth, inserts, etc.

The furniture fasteners discussed in the article are the most common and most frequently used, due to the fact that these are the most versatile and easy-to-use types of fasteners. In the vast majority of cases, the types of furniture fasteners described are sufficient to assemble any furniture.

What drills are needed to make furniture with your own hands?

Drilling is one of the important stages of furniture manufacturing, requiring accuracy and utmost care. In production, to facilitate the marking process, they use additive machines and special furniture templates (gearboxes). At home, you will have to be content with a tape measure, a square and a marker to mark the locations of future holes for certain type fasteners Each type of fastener requires specific drills for furniture making. In some cases, you can limit yourself to the minimum set. For example, if your goal is to make a simple shelving rack with your own hands, then you can get by with a set of two ordinary drills with a diameter of 5 mm and 8 mm, which any “home” craftsman will probably have - in combination they completely replace a specific drill for confirmations. But if the goal is to implement a larger-scale project, you will need other drills for making furniture.

Marking drills for furniture assembly

Typically, a marker and an awl are used to mark the location of the basting hole. Can you use thin drill diameter 2.3 mm. It will also be needed during the installation of fittings on self-tapping screws - for example, guides, hinges, gas lifts, legs, etc. This will allow you to perform all operations more accurately and accurately, which means that problems with on-site adjustment due to crookedly screwed fittings can be avoided.

Drills for confirmation (euroscrew)

The specific shape of the confirmat drill, with a characteristic expansion from a diameter of 5 mm to a diameter of 8 mm, allows you to make two holes at once in one go, for the narrow and wide part of the Euroscrew with a countersink for the head. "work" with it view of drills both with front and horizontal parts, drilling the end furniture panels and facial details. It is important not to confuse the “face” with the “wrong side” during the process - otherwise, it will be difficult to hide untidy chips instead of a neat countersink into which the confirmation hat will “sink.”

Drill bits for furniture making 5 mm

The most popular after confirmation. Used for through and basting drilling when installing handles, shelf supports, eccentric rods with a self-tapping head, dampers and other fittings. Some craftsmen prefer to use a drill with a diameter of 5 mm to drill the ends of the front parts made of chipboard for connecting with confirmation mats.

Drill bits for furniture making 8 mm

Used for drilling holes for eccentric tie rods, dowels, mortise push-ups (pushers and shock absorbers), glass holders, shoe rack pins and specific flag canopies. And, as was written earlier, the combination of 5 mm and 8 mm drills makes it possible not to use a confirmatory drill during the additive process.

Drills for furniture barrel ties 10 mm

A thick furniture drill with a diameter of 10 mm is rarely used. But you can’t do without it when installing barrel ties, reinforced eccentric casings, some types of mortise pushers and smooth-running dampers, and hidden hinges. It is also convenient for them to make holes in the walls of furniture for the output of wires when installing lighting.

Eccentric drills 15 mm and 20 mm

To install the eccentric body itself, you will need a drill with a diameter of 15 mm; if the eccentric is reinforced, then with a diameter of 20 mm. An eccentric drill is also useful for installing some types of shelf supports and locks, some rarely used fittings (study the installation instructions).

Drill for hinges 26 mm and 35 mm

Four-hinged furniture hinges come in two types - with a standard bowl of 35 mm and a reduced bowl of 26 mm (rarely used when there is not enough space to install a regular canopy). For holes for furniture hinges, the most common drill diameter is 35 mm. It is also useful when installing countertop ties and some types of supports.

Drill for plugs for cable channels and lamps 60, 65 and 85 mm

IN office furniture special ones are often used plastic plugs round shape for cable ducts, built-in sockets for installation in kitchen countertops. For this type of hole you will need a plug drill with a diameter of 60 mm. It is also useful for drilling holes for built-in lamps. In the latter case, it is better to clarify the diameter of the selected lamps - it may well be necessary furniture drill with a diameter of 65 or 85 mm.

Choosing a furniture screed depending on the type of structure

Furniture has always been made from individual elements, which are then assembled in a certain sequence. Previously, furniture screeding was carried out using locking joints, tenons and wedges, however, for simple home furnishings this was enough. Similar connections are still used today in the manufacture of antique-style furniture. In modern furniture production, fasteners are represented by a wide range of elements. This makes it possible to produce furniture of various shapes with complex joining methods.

When assembling a furniture product, the location of the connected parts of the structure must be checked so that its integrity is not compromised during operation. This is what a furniture tie is intended for - a fastener that makes it possible to tightly and firmly connect structural elements located in a certain position (most often at a right angle) relative to each other. If previously furniture was assembled mainly using screws and self-tapping screws, now different types of ties are used for this.

This replacement is due to three reasons:

1. Increasing the aesthetics of furniture, thanks to the use of ties, the fastening of parts becomes invisible;
2. Each disassembly of furniture assembled with screws reduces reliability;
3. Sometimes the use of conventional fasteners is simply impossible for structural reasons.

And finally, the use of furniture ties allows for quick and durable assembly of the product.

Types of furniture screed

Depending on the purpose of connecting parts, different types of furniture ties are used. They differ in external design and the material from which the fasteners are made.

Confirmat

Simple and convenient use has made confirmat (or euroscrew) the most common type of fastener. This euro-screed consists of one element - a euro-screw, which can be called a reinforced version of the self-tapping screw. Its shaft is slightly thicker, has a blunt end and a massive, widely protruding thread. Thanks to the notches on its lower turns, the Euroscrew, when tightened, cuts a chamfer in the finished hole. This makes it come into even closer contact with the material being fastened.

The confirmat can be used to connect two furniture panels located at right angles. To do this, holes are simultaneously drilled on both panels: for the countersunk head and for the screw thread. It is better to drill them with a special drill for confirmat furniture screed. The countersunk head has hexagon slots.

It is not recommended to screw in confirmations with a Phillips screwdriver, since it is impossible for it to screw them all the way. If holes are pre-drilled in all parts of the furniture structure with a special drill for furniture screed, the furniture can be assembled with a confirmat faster than with any other type of fastener.

Eccentric coupler

When connecting L-shaped or T-shaped furniture elements, eccentric couplers are used. This fastener consists of three parts:

1. A rod having a head;
2. A special clamp called an eccentric;
3. A plug that creates a decorative effect.

The advantages of such tightening include the secrecy of the fastener (the hole is not drilled on the front side of the furniture) and the possibility of its repeated use without the risk of damaging structural elements. Due to the complex drilling, which requires a furniture tie drill to drill blind holes, eccentric fasteners are often performed in the factory. For the eccentrics you need to drill holes with a flat bottom; this is easier to do with a Forstner drill.

Intersectional screed

Intersectional furniture screed is necessary for tightening individual sections, for example, cabinets in the kitchen, into a single block. This threaded connection is equipped with a screw and a bushing. A through hole is drilled in the side walls of evenly aligned cabinets, a bushing is inserted into it on one side, and a screw is screwed into it on the other. Although both heads of the Phillips screwdriver are notched, it is the connecting screw that must be tightened, not the bushing. The notches on the sleeve are made to hold it so that it does not rotate in the part. You can tighten a pair of cabinets using 2 - 4 intersectional fasteners, which are best placed closer to the corners. Depending on the wall thickness, fasteners of different sizes are used.

Corner ties have been used in furniture production for quite a long time. This connection is made up of five elements:

1. A corner in the form of a metal plate bent in the middle at a right angle;
2. Pairs of bolts;
3. Two footwear.

To connect two panels with a corner tie, a corner is placed at the point where they meet. Then the fittings are inserted and the bolts are screwed in, first to one panel, and after trimming the connection, to the second. In its finished form, judging by the photo, such fixation can hardly be considered aesthetic. Therefore, today, whenever possible, corner fasteners are replaced with other furniture ties, for example, minifix or confirmat. Their dimensions are much more compact than a metal corner plate.

Screw coupler

Furniture screw fasteners are used when the end of one part needs to be attached to the surface of another. This fastener has only two elements: a screw and a barrel. A threaded hole is made in the side of a cylindrical metal barrel. In some screw ties, the barrel is made of plastic, then a nut is placed inside it. When installing this fastener, a couple of holes are drilled on the surface and at the end of the panel. A barrel is inserted into the first one so that the holes on the barrel and the end are aligned. The screw is threaded into a through hole drilled in the surface of another panel. The large tightening stroke makes the fastening particularly durable. The aesthetic error of this type of screed is considered to be the visibility of the screw head on the front side of the panel.

Conical coupler

The conical tie is an improved version of screw fastening. To hide the screw head on the front side of the panel in the conical connection, the screw was replaced with a rod. Unlike a screw that goes through the panel, the rod only screws into it. This reduces the tightening stroke and makes the fastener less durable.

Table top screed

In the manufacture of kitchen furniture, furniture table screed is used. When the tabletop is assembled from two parts, paired fasteners are installed. Why use a Forstner drill to mill one hole in each part of the tabletop. A groove is cut between the holes using a chisel. Clamps are placed in it. A tension head with a C-shaped washer is placed in one blind hole. Then, using a wrench, begin to tighten the C-shaped nuts.

Furniture dowel

The simplest type of fastening is a dowel. This connecting element looks like a short piece of pencil made from a piece of wood. Today, when assembling furniture, the dowel complements the eccentric tie to give it greater rigidity, and it is rarely used as an independent connecting element.

How to choose the right screed

Choosing a suitable furniture tie is of great importance when assembling furniture. The final result in the form of a finished product depends on it. There are quite a few types of screeds, so each case requires an appropriate approach to assembly. The selected type of fastener should not interfere with the operation of the furniture or spoil its appearance. To ensure these conditions, it is necessary to choose the right furniture screed and not violate the assembly technology.

Cabinet furniture pieces are mainly designed to store various things. Therefore, when assembling them, it is necessary to ensure the strength of the connections. Confirmat screed is best suited for this. This fastener allows you to connect parts at the desired angle. And thanks to the holes for Euroscrews, drilled using a special drill for furniture screed, Confirmat ensures high-quality assembly of cabinet furniture. The main disadvantage of confirmations is the unaesthetic appearance of the hats, which, although they remain flush, are still very noticeable.

An eccentric tie is another type of fastener used in assembling cabinet furniture. It is used where it is necessary to hide fasteners, for example, on the facade of furniture. The main advantage of eccentric fasteners is hidden installation.

Its high load-bearing capacity is due to its design. Cabinet furniture is a prefabricated structure consisting of several pieces of furniture connected to each other. This necessitates the use of an intersectional tie, which is designed to tighten adjacent pieces of furniture.

The main purpose of upholstered furniture is comfortable rest. Therefore, it should be comfortable, practical and last long enough. Fastening of upholstered furniture with a carriage screed must be reliable and have an aesthetic appearance. Ideally it should be invisible. All these requirements are met by a furniture bolt with an eternal companion, a nut. With such metal fasteners, the furniture will withstand the mechanical loads exerted on it during operation. In addition, the semicircular head of the bolt, which protrudes slightly above the surface of the parts, will be completely invisible under the upholstery, especially if there is a carriage tie on it.

Built-in furniture is designed to store things and objects for various purposes. Very often, such structures consist of only shelves installed in niches or along the walls. Therefore, the best fasteners for them can be confirmations and furniture corners. If the design of built-in furniture does not provide for the installation of facades, it is advisable to use eccentrics and minifixes as fasteners. These fasteners are installed without through drilling, which allows you to maintain the aesthetic appearance of the structure.

Today, furniture in which individual parts are made of glass sheets is especially popular. They are quite fragile, so glass furniture fasteners must have a large margin of strength and are naturally made from other materials. For this reason, it is better to use special types metal fasteners (clamps, holders) complete with rubber gaskets. To install them, not only drilling is used, but also fastening with glue.

Furniture confirmations: dimensions, drills and holes for euro screws (euro screws)

Confirmat is the most popular fastening element used in the production of cabinet furniture. Confirmations became widespread back in the 90s of the last century and since then have been actively used by specialists working in furniture production.

Confirmats are great for assembling homemade furniture

The correct name for this fastening element (along with the designations “Euroscrew”, “Euroscrew”, and sometimes simply “Euroscrew”, which are common among home craftsmen) is “single-element tie”. The word indicated in the title comes from the name trademark Confirmat, which the German company Hafele began to use in the production of fasteners of this type.

Design features and advantages of use

Confirmats are screws equipped with a countersunk head, which has two types of slots. Thanks to the presence of these slots, Euroscrews can be tightened with either a four- or hexagonal screwdriver. The rod of such a screw has a blunt end, and its working part has a widely protruding thread. Bottom threads are designed to cut threads into a pre-prepared hole, so they are conical and serrated. Under the head, the Euroscrews have a smooth (no thread) surface.

Significant parts of the confirmation

All confirmats have a protective coating of zinc, brass or nickel, and are made from high-quality carbon steel. The use of such steel makes it possible to give Euroscrews high ductility, due to which they bend but do not break. The high plasticity of confirmats ensures their easy removal from furniture even if their installation is carried out incorrectly.

The use of confirmata allows you to connect furniture elements made not only from natural wood, but also from its processed products - MDF and chipboard. Based on the ratio of the outer diameter of the thread and the length of the screw, fasteners of this type are presented on the modern market in the following standard sizes: 5x40, 5x50, 6.3x40, 6.3x50, 7x40, 7x50, 7x60 and 7x70 mm. The most popular are Euroscrews, the length of which is 50 and 70 mm, and the thread diameter is 7 mm.

Sizes of common confirmations

There are varieties of confirmations produced with a regular cap. When using them, additional countersinking of the hole is required. Certain categories of confirmats are made with a special tooth located under the cap. The purpose of such a tooth is to form a chamfer in which its head will be located when installing the fastener.

If the confirmation hat is on the front side of the furniture product, it can be disguised using decorative plug or stickers that are in today large assortment offered by any hardware store. When choosing such decorative elements, you should take into account not only the size of the Euroscrew head, but also the texture and color of the furniture structural elements that are connected with it.

The diameter of the securing decorative protrusion of the plug must match the size of the recess in the confirmation cap

How to fasten with Euroscrews

To use confirmations, certain skills in working with such fasteners are required, as well as knowledge of the characteristics of the material from which the products being connected are made. Drilling for confirmation is performed with a tool whose diameter is 4.5–5 mm. In this case, it is best to use drills that have a stepped cutter attached, which allows you to immediately chamfer the location of the screw head. Using such a tool, you can get a finished hole in one pass. The cutter in this case forms perfect surface under the screw head, which cannot be said about the drill, which, when removed, can leave chips on the edges of the hole (they, however, will subsequently be covered by the confirmation head).

Euroscrew installation sequence

Euroscrews, when compared with other types of fasteners, provide more reliable fixation of the parts being connected. This is explained by the wider arrangement of threaded elements, which reliably cut into the material. Install confirmations manually, as well as using an electric drill with appropriate attachments or a screwdriver. For those who do not have experience working with such fasteners, it is better to install them manually, so that in case of excessive resistance of the screw, they can be able to remove it from the furniture elements being connected at any time.

How to drill a hole for placing a confirmat

The confirmat is screwed into a previously prepared hole, so the question of how to drill such a hole is quite relevant. To do this you will need the following tools and materials:

• screwdriver or electric drill;
• bit of the appropriate size;
• drill for confirmation;
• a measuring tool, which can be a ruler (or a construction tape);
• pencil;
• awl.

To facilitate marking and maintain a strictly perpendicular position of the drill, use a template for drilling holes for confirmat

Hole dimensions for Euroscrew

For furniture assembly, Euro screws are usually used, the dimensions of which are 6.4x50 mm. To make holes for such confirmation, outside diameter whose thread is 6.4 mm, and the size cross section the screw body is 4.4 mm, a drill with a diameter of 4.5–5 mm is used. Drilling holes for confirmation of this type should be performed to a depth of at least 50 mm. If the diameter of the hole is larger than the specified value, then the Euroscrew simply will not hold; if it is smaller, it can tear the furniture element into which it is screwed.

Step drill selected based on the dimensions of a specific Euroscrew model

The drill used to make holes for the confirmation must be equipped with a special working head. On the one hand, she prepares an expanded hole for the neck of the screw, on the other hand, she countersinks the place where the screw head will be placed. To place the confirmat, you can also use a regular drill, but in this case it is necessary to prepare places for the neck of the fastener and its head.

Marking drilling locations

The reliability and quality of connections made using confirmats largely depend on the accuracy of marking future holes for them. On the element that will overlap the end of another element of the furniture structure, two types of markings are made:

• drilling depth (5–10 cm);
• the center of the future hole (if the thickness of the joining part is 16 mm, it should be at a distance of 8 mm from the edge of the slab).

Drilling diagram for Euro screws

On the joined element, the drilling point is marked at its end, placing it strictly in the middle of the furniture board.

To mark the drilling locations as accurately as possible, you can use the following simple technique: after preliminary marking, a through hole is made in the applied part, through which, by attaching the first part to the second, a rotating drill is used to mark the location of the second hole for the European screw.

Making holes

In order to make the holes for placing confirmations as efficiently as possible, it is advisable to follow the recommendations below.

1. Before drilling a part, you need to place a piece of unnecessary chipboard under it: this will prevent chips from appearing at the exit of the hole being created.
2. The formation of places for the neck and cap of the confirmat in an already made hole can be done by holding the workpiece in weight.
3. When drilling both in the layer of the part and at its end, the drill is positioned strictly perpendicularly. This will allow you to get a high-quality result and not damage the part.
4. When drilling two parts simultaneously, they must be securely fixed in the required position, for which you can use clamps and other clamping fixtures. This is the most accurate and quick way creating holes for confirmations.
5. When drilling holes for dowels, it is advisable to equip the tool used with a depth limiter, which will prevent damage to the workpiece by drilling through them.

The quality of furniture assembly and the reliability of its operation are largely influenced by fasteners designed to connect individual elements to each other and used for installation of products. Of course, the type and design features of the fasteners depend on the category of furniture and the conditions of its use.

Modern industry offers a sufficient number of new fastening accessories that greatly facilitate the assembly of furniture and increase the durability of its use in the most unfavorable conditions. For example, kitchen samples made from cheap particle board, are more likely to be destroyed by panel delamination or peeling decorative covering than they will fail due to poor quality or reliability of fasteners.

Today, in the industrial and independent production of furniture products, many types of fasteners are used, differing in functionality, method of fixation, size and protective coating.

Fastener categories

If half a century ago the main elements for assembly components furniture were wooden dowels, and installation of various pieces on site was carried out using nails or screws, today the range of accessories for connecting individual parts and elements of furniture has expanded significantly.

Modern fastening and connecting parts can be divided into several categories, including both highly specialized products and universal fittings:

The most common types of furniture fasteners

Let's consider the most common groups of connecting and fastening fittings for furniture, the features of their installation and operation.

Button or decorative head screws and bolts with a fixing mustache or carriage are the main types used for fastening individual panels of frame furniture. Thanks to the fixing mustache or square head, the bolt (screw) is fixed in the hole of the particle board, which prevents it from turning. Due to this design feature, the assembler has the ability to tighten the nut without additional fixation of the screw.

Universal screws with countersunk or semi-countersunk head have splines various shapes(cross, with internal hexagon, straight slot and others) and intended for fastening individual assembly parts inside furniture structures. They are used for:

On a note!

When using universal screws, either screwdrivers with replaceable bits or sets of screwdrivers with replaceable tips are used.

Confirmats (europrops) in modern furniture production they are the most popular type of fastening and fixing devices. This type is used for fastening any parts made of chipboard or MDF panels.

Before screwing in the Euroscrews, holes are pre-drilled in the parts using a special confirmatory drill, the diameter of which depends on the diameter of the fixing element. To screw this type of fastener, use either special bits or screwdrivers with seed tips. The type of bit or attachment depends on the type of slot.

Eccentrics other accessories, bearing the somewhat exotic name of rasteks and minifixes, allows you to connect and attract panels located at right angles to each other. Despite the obvious advantages of this category of fasteners, their main disadvantages are:

• need for additional milling furniture panels, for installing individual fasteners;
• relatively high cost.
• high precision of marking and difficulty in installing individual fasteners;

On a note!

To install individual minifix parts, you will need three different types of woodworking tools - one end mill and two drills of different diameters.

Furniture corners have proven themselves to be a reliable, easy-to-install element. Today they can be made either of metal or of special, high-strength plastic. In industrial production, the color of the plastic corner is matched to the color of the furniture.

Modern furniture dowels made of wood, plastic or metal. Their main advantages are low cost and ease of connection. furniture parts between themselves. To increase the reliability of the connection, there is a corrugation on the surface of the dowels.

Special types of fastening accessories

Today, furniture, individual parts of which are made of glass sheets or in the form of mirrors, is becoming increasingly popular. If ten years ago glass was mainly used as doors furniture cabinet and showcases or doors of racks and shelves, then today glass table top magazine or dining table you won't surprise anyone.

To connect glass parts and furniture elements made from other materials, special types of fittings are used, which are attached to glass surfaces using special adhesive compositions, by wrinkling the clamps with rubber gaskets or by drilling holes in the glass. When choosing this category of fittings, you must pay attention to the weight that it can withstand, which is specifically stated in the instructions for its use.

This review will focus on new furniture fittings.

All generations of furniture ties. Start

Connecting fittings- the most important component of cabinet furniture, therefore, the usually invisible screed has become today one of the main elements of furniture, ensuring its strength and durability.

History of the "connection"

In ancient times, furniture making was not very different from carpentry. When connecting its parts, the same techniques and methods were used as in the construction of a hut or a church: castle joints, tenons, “shkans” (now - dowels) and wedges that gave strength to benches and tables. Making such connections manually is quite a labor-intensive task. The parts were held together by a tight connection with glue, the accuracy of which was ensured by eye, and it was necessary to masterly use a saw and a chisel so that they fit exactly against each other. Similar combinations can still be found in antique-style furniture, but rather as a decorative element that makes retro-style furniture only look like it was made by the hands of experienced craftsmen.

Since those times, only dowels(8X30), however, also acquired different sizes, received corrugation and a precise chamfer at the ends. Everything else gave way to special fittings. Connecting furniture on dowels even now gives us the opportunity to quickly and correctly position furniture parts during assembly, and prevents their mutual displacement during operation, absorbing all lateral loads. A dowel is a very cheap and simple part, but it also has its own difficulties. It is made from natural wood and, when made from undried wood or improperly stored, can change its cylindrical shape, which significantly affects the quality of the connection. However, small furniture is connected using dowels alone. With large product sizes and correspondingly increasing loads, the dowels can no longer withstand pulling out, that is, longitudinal forces, and therefore, ties can always be found next to them.|

Types of screeds

Corner coupler UC11

Principle of operation:

The product is also very simple in design: a strip of metal bent at a right angle with a hole on one arm and a groove on the other. It consists entirely of five elements: a corner, two screws with countersunk heads and two threaded fittings. During assembly, the angle is attached with screws to the parts being connected using metal or plastic fittings with an internal threaded hole. The tightening force is achieved by displacing the axis of the fastening hole on one of the parts being connected. As a result, when screwing the screw, it presses the cone of its head onto the cone lateral surface holes in the corner, displacing the entire attached part and attracting it.

Advantages:

At one time, this screed even became widespread in our industry, because:

• durable;
• does not require drilling holes in the ends;
• easy to install;
• unpretentious to the accuracy of the location of filler holes;

Some furniture makers even managed to use such a tie without dowels in the connection at all!

Flaws:

• visible;
• interferes with the use of furniture (for example, it will not be possible to place the box in a closet close to its wall, and when removing it, it can be torn or scratched;
• there are a lot of defects in its production;

As for attempts to use metal or plastic corners secured with screws to connect furniture parts, it is better not to buy furniture with such connections: this is not a screed at all, and you will get a reliable tension gusset They cannot be used in any furniture.

Screw tie KON 7x50 (Euroscrew)

Story:

This screed became known to domestic furniture makers back in 1973 from the catalog "Der Grosse Hafele" under the name " Confirmat". It was always intended only for assembly small-sized furniture. Today it can be found in the same catalog, under the same name. But today the same ties are produced by many companies: "Hettich" ("Direkta 2"), "Dresselhaus" ("Unita Stahl"), etc., and even domestic enterprises.

In Europe this screed is called " Einteilferbinder" or " single-element screed (single)"And for some reason we call it " Euroscrew" or " Euroscrew"Although the name would suit her much better" screw tie", especially since it is like two peas in a pod and looks like a screw, only thick and dull.

Principle of operation:

The simplest screed, which has found such wide use among our furniture makers precisely because it does not require practically any precision at all when adding. Only two holes are drilled: one in the end of the main part, the other in the face attached to it.

The most popular are Euroscrews with a thread diameter of 7 mm and a length of 50 or 70 mm. Ties different manufacturers have their own design features. The small diameter of the head often allows, using force, to embed the screed flush with the surface of the slab without first countersinking the hole. Also, screw ties may have a specially provided “tooth” under the head, similar to a flash in a poorly made nail, which ensures that it is screwed in flush without countersinking, forming a chamfer for the hole.

A high-quality screed should not have a displacement of the head or slot relative to the axis. If this alignment does not exist, then the tie will go unevenly when screwed in, and the thread will break the hole, which impairs the strength of the connection between the chipboard parts. A tie with a smaller pitch of turns and a larger thread point provides a more durable connection. The first four turns of the thread are conical and have special serrations. Therefore, the tie works like a tap or self-tapping screw, ensuring the cutting of smooth, high-quality threads to accommodate the remaining turns without disturbing the structure of the slab.

Flaws:

• head visible from the end. It is usually closed with a plug;
• furniture assembled on such a screed cannot be assembled more than three times, since the threads cut in such a soft material as chipboard are likely to break. The trouble is that many manufacturers, rightly hoping for the strength of the metal, have completely stopped using dowels together with this screed. But if the assembly is carried out without securing the parts in the clamp, then the parts may “lead away,” which can be noticeable when inspecting some products;

5. Eccentric coupler(EC02 + rod (TE 03) + fitting (BU 01))

Despite the popularity of the screw tie, all the highest quality modern furniture assembled using eccentric couplers.

Principle of operation:

A metal or plastic sleeve is screwed or pressed into the face of the attached part, flush with it, into which the tie rod with a “T”-shaped head is screwed. When assembling the product, the rod passes through a hole in the end of the main part, and its head ends up in the middle of a transverse hole drilled in its face. An eccentric is installed in it, gripping the rod head with its internal eccentric surface. With further rotation, the eccentric, turning in its hole and acting on the head of the rod, first brings the parts to be connected together, and then creates the necessary force in the connection.

An eccentric coupler consists of a cast metal eccentric, a fitting and a rod. There are also quite a lot of designs of such couplers, in which the rod is wrapped directly into the material of the attached part, without the use of a sleeve. The main difference between eccentric couplers is the diameter of the eccentric. The larger it is, the greater the stroke of the tie and the greater the possible force. Eccentrics with a diameter of 25, 15 and 12 mm are used. Eccentrics with a diameter of 25 mm, and sometimes 15 mm, must be closed with a plastic plug.

Flaws:

• possible weakening of the tie during operation of the product. Different manufacturers solve this problem in different ways. For some couplers, the internal working surface of the eccentric is made concave, and the spherical working surface of the rod head is in contact with it. In other designs, the internal working surface of the eccentric is stepped, and the adjacent working surface of the rod head is flat. Wherein outside surface The eccentric is equipped with oblique smoothed teeth, inclined in the direction opposite to the direction of its rotation during assembly, which, while increasing adhesion to the material of the part, additionally prevents its spontaneous rotation and loosening of the connection during operation of the product. Also, the notches inside the eccentric increase its adhesion to the rod three times compared to a smooth flat surface;
• The eccentric coupler requires extremely precise relative position all mating holes. Drilling these holes "on the knee" often leads to breakage of the eccentric when applying force during assembly. Actually, the lack of precise filler equipment limits the widespread use of eccentric couplers in domestic furniture;

Types of eccentric couplers:

There are many varieties of eccentric couplers designed to solve different problems. For example, with the same, most common diameter of 15 mm, the eccentric can have different heights so that, regardless of the thickness of the part, the hole for the rod can be positioned exactly in the middle of its thickness. And this makes it possible to provide a smaller number of standard sizes of parts when adding.

One way to avoid the complex alignment of the axes of holes in the face and end is to use eccentrics in the body (SE 01 + rod (TI 04)). The eccentric is installed in a hole drilled in the face near the end of the part, so that an opening is formed at the end of the part, into which a part of the eccentric body with a hole for the rod emerges. In this case, the tie rod is shorter, and the eccentric axis is located closer to the end of the main part, but thanks to the design features, the tie can be tightened by positioning the screwdriver at an angle to the face. The outer casings of such ties are made of plastic of various colors, or metal (a more expensive and beautiful option).

This tie has found its application as a shelf support. But, unlike inset shelves installed on conventional shelf holders, shelves using such eccentric ties are always a strength element of the structure, which increases the strength and rigidity of the entire product, and this is especially important for heavily loaded office furniture. The eccentric is placed in the body material, which is stronger than the plate from which the furniture is made. Therefore, repeated rearrangement of the shelves does not lead to wear of the eccentric hole and weakening of the connection.

Reinforced eccentric with additional bushing SE07

For especially loaded, heavy shelves there is a reinforced eccentric in an elongated body with an additional fitting (SE 07), for which a separate hole is provided. Such a screed is held even better in the chipboard, and the futorka stabilizes the shelf, preventing it from moving relative to the sidewall.

Conclusions:

The article discusses only the main types of ties for connecting furniture parts. You can view the full range of MDM-Komplekt furniture ties in the electronic catalog or in the office. The main thing when choosing a screed is to understand that it is not just a connecting element in furniture, but a mechanism that creates force between parts, due to which the furniture acquires resistance to external loads and the necessary strength.
