Types of furniture joints
To assemble furniture, two types of fastening can be used:
- furniture screws;
- confirmations.
Confirmat is one of the varieties of furniture screws; it is also called a screw tie, euroscrew and euroscrew.
The self-tapping screw has a sharp end and a small thread pitch, while the confirmat has a wider pitch and a larger rod diameter. The first type is most often used when assembling interior items made of solid wood, plain and laminated chipboard, and MDF.
This type of fastener, known as a self-tapping screw, is a type of metal screw with a screw thread and a pointed or flat end.
Confirmat has recently become more widely used; it differs from a self-tapping screw primarily by its expansion after the end of the thread when moving to the part with the fastening head. In this simple way, a higher quality screed is achieved.
Elements such as furniture confirmations are in considerable demand due to the incredible precision of their fit and ease of use.
While a self-tapping screw can be screwed into a panel with a regular screwdriver without pre-prepared holes, this cannot be done with a confirmat.
To install it, you will need a hex wrench or a drill with a special attachment.
Universal screws
Furniture screws allow you to obtain an acceptable quality of screed and an accurate connection, but when working with this type you should not make mistakes. A slight misalignment when fixing such fasteners - and both fastened elements can be damaged.
Self-tapping screws do not withstand repeated unscrewing from the same hole, so if you make a mistake at the preparation stage, you will have to drill out the space for the fastening element again.
The head of the element has a notch (straight, cross or polygonal) for twisting it into the fabric.
Also, most often the diameter of the self-tapping screw is inferior to the confirmat, so an equally reliable and durable tightening of the parts together is not achieved.
To quickly connect parts of a cabinet or other item, use a screwdriver for elements with a sharp end.
Depending on the material, the screw can be metallic, black or golden. Thanks to this, such fasteners can be easily masked without additional elements, only due to their own color.
Self-tapping screws are used to fasten parts without prepared holes or with them. Due to the thread, the screw is easily screwed into a wooden panel or chipboard.
Confirmations
As already mentioned, confirmats are able to provide higher quality screeds. A rather significant disadvantage of this type of fastener is that it cannot be used with material of shallow depth. It is this factor that limits the use of confirmat, but in most cases they are used for cabinets, tables, sets and countless other types of interior items.
Confirmats allow you to fasten together several parts made of natural wood.
Note! If you plan to use fasteners in aggressive conditions, especially high humidity, the confirmat must have anti-corrosion protection.
For its production, exclusively high-quality carbon steel is used.
Has an anti-corrosion coating based on zinc, nickel or brass. The shape of the confirmatory head is selected according to individual preferences. The only caveat is that if you plan to cover the surface of the cap, you should select elements that match its shape.
Advantages and disadvantages
One of the main advantages of using a special fastener is the eccentric tie, which provides, on the one hand, reliable fastening, and on the other hand, can be easily hidden from view.
They are especially often used for assembling cabinet furniture, ensuring a sound and durable connection of structural parts.
The most common disadvantage is the hex head, for which it is necessary to purchase the appropriate tool. And this is almost the only negative that can be found.
The selection of self-tapping screws is influenced by the type of construction and the desired appearance of the product.
detailed instructions
Step 1. You need to indent approximately 7-12 cm from the upper and lower edges of the door. In this case, the indentation in the instructions is made at a distance of 8 cm. You need to draw two lines strictly perpendicular to the edge of the door.
An indentation of 8 cm is made
Lines are drawn perpendicular to the edge
Step 2. Next, from the edge of the door to the center of the place where the hole will be drilled, you need to make an indent of 22 mm. This is the standard distance. And you also need to draw lines through the marked point, perpendicular to those drawn earlier.
Bottom space - 2.2 cm
Perpendicular lines are drawn
Step 3. Next you need to take a special drill with a standard diameter of 35 mm.
Take a drill with a diameter of 35 mm
Step 4. To make drilling easier and the drill clearly positioned, you need to make small notches using an awl at the intersections of the lines on the markings.

Step 6. Once the holes have been drilled, you can try on the hinge bowl, and also, by aligning the holes for the screws on the ears of the bowl along the line drawn earlier, mark where the drilling will be done, but with a thin drill. Moreover, the points will not be on the line itself, but slightly to the side, with the ears aligned along the line.

Markings have been applied for future holes
Step 7. Now, using an awl, you need to make notches at the designated points to position the drill.
Notches are made to position the drill
Step 8. Next you need to drill holes for self-tapping screws measuring 4x16 mm.
Holes are drilled
Step 9. It is necessary to attach the canopy to the door again, placing the bowl in the hole, and screw it to the facade with self-tapping screws.

Step 10. Now you can attach the door to the cabinet wall. This is done like this - first you need to attach the door to the wall, choosing the position in which it should stand.
Now you can attach the door
Step 11. When applying markings, you need to ensure that the upper hinge screw, which will be attached to the wall, is in a position close to the door itself.
You need to mark carefully
Step 12
Next, it is important, after taking simple measurements, to set aside 17 mm from the center line on which this part of the canopy lay.
From the center line you need to set aside 17 mm
Step 13. After this, you need to attach the door again and make marks with a marker through the holes in the hinge, aligning them with the lines drawn at a distance of 17 mm.
Markers are used to make marks through the holes in the loop.
Step 14. Now you need to drill holes for Euro screws with a drill.
Holes for Euroscrews are drilled
Step 15. Next you need to screw part of the loop to the wall.

Step 16. Then you can attach the door to the wall
It is important to get the front part of the hinge attached to the door onto the screw located on the part of the hinge that is fixed to the wall. Also, under the hinge that is attached to the door, there is a screw with a “heel”, which is important to get into the groove located on the other side of the part of the hinge that is attached to the wall
This part needs to get onto the screw

Step 17. To prevent the hinges from coming apart, the outermost screws need to be tightened a little. There is no need to wrap them all the way yet.
The outer screws are tightened a little
Step 18. Now you need to adjust the door. To begin with, you should move it away from the cabinet wall by about 1-2 mm; you do not need to fix it tightly to it. Once the gap has been maintained, the screws can be tightened.
Door adjustment
Step 19. There is another screw that will help you move the door left or right if necessary. In this case, there was no need to adjust it.
This screw in our example did not need adjustment

It is important to remember that after some time the hinges will have to be adjusted again - the doors may sag under their own weight. So you still need to tighten the screws the first time. Sometimes you should also lubricate the hinges - then they will definitely not begin to creak or rust over time
If the furniture is in a damp room, the service life of the canopies is greatly reduced, and this is important to take into account.

Overview of species
Based on the design and size of the furniture fronts, suitable piano hinges are selected. There is no special classification for card loops. In many ways, they are divided according to the material of production. Here you can highlight designs made from:
- become;
- brass;
- nickel;
- stainless steel (stainless steel);
- aluminum;
- alloy using all kinds of galvanizing.
In the version with zinc, the technology of galvanizing various alloys is practiced. A galvanized loop can be either brown, black, red, yellow, white, or accurately reproduce gold, silver, bronze and more.
Steel has the highest strength and is sold at a reasonable price, but it is not resistant to rust in unstable conditions. Such hinges are recommended for use in a controlled environment, for example, inside buildings, where normal levels of temperature and humidity are maintained.
Stainless steel is also very durable, and it is also resistant to corrosion in wet and outdoor environments. Non-corrosive card loops meet hygiene requirements, which makes it possible to use them in food and medical equipment. In addition, they have a beautiful satin finish or have a glossy polish.
Brass does not rust, is resistant to oxidation and is very decorative. But it has less strength when compared with steel and stainless steel. Aluminum is a lightweight metal with high anti-corrosion characteristics. Aluminum hinges are aesthetically pleasing and inexpensive, but under significant loads they can bend, making them unsuitable for use in heavy door systems.
More products can be systematized by size, dividing them by length, width and thickness
It is recommended to pay attention to the thickness characteristics. There are ordinary loops or reinforced ones made of thicker material
How to choose the right self-tapping screw
First of all, in this matter we start from the material that needs to be fastened. For a thin sheet of solid wood plywood, the use of confirmations is impossible. The main criterion for choosing self-tapping screws is their availability.
The length of the screws can reach up to 50 mm and above. These fasteners are designed for thick solid wood panels.
For the lion's share of furniture assembly work, especially when working on a large project, confirmat is the best hidden fastener for chipboard furniture.
Furniture confirmations have a large rod and threaded surface, due to which the load on the material being fastened is small.
With our help, choose the most suitable fasteners for your furniture. You can be completely confident in the quality and durability of such fastening.
The use of confirmations will allow the structure to withstand significant loads for a long time.
