Confirmat screws are a type of assembly screw commonly used to connect various elements together. They are most frequently found in desks, cabinets, bookcases, and drawers. Their construction guarantees a very durable connection. See all the information about these fixing elements below.

What are confirmat screws?

Confirmat is a name that may initially seem puzzling to many people. It originates from the Latin language (lat. confirmare) and has several meanings. Among them is the meaning "to strengthen", "to confirm". Confirmat screws owe their name to the fact that they are used to create very strong joints.

According to modern definitions, a confirmat is a type of metal screw used primarily for furniture connections. It establishes a rigid and secure joint between two components. The confirmat-style assembly screw is distinguished by its specific shape. Due to the intended purpose of confirmat screws, steel, galvanised steel, nickel, and aluminium-zinc alloys are primarily used in their manufacture.

What sizes of confirmat screws are available?

Confirmat screws are available with cross-recess and hexagonal socket drives. They are available in both natural and coloured finishes. Standard screw diameters are 6.4 mm and 7.0 mm, but you can also find assembly screws in other sizes. One of the most popular non-standard sizes is 7.9 mm with a length of 33 mm.

How and what are confirmat screws used for?

Alongside their robustness, confirmat screws are characterised by their relatively large diameter. Both fully threaded and partially threaded screws are available on the market. In the latter case, the smooth section of the screw usually covers no more than approximately 1/3 of the screw length.

Confirmat screws are commonly used to join chipboard, plywood, and other timber components. They are suitable for connecting wooden parts rigidly and at right angles. Assembly screws are also used by DIY enthusiasts to construct various clever designs themselves. Their application is exceptionally versatile, making them suitable for many assembly tasks in the hands of a skilled hobbyist.

What types of confirmat screws are there?

This type of screw differs from others due to a modified cutting edge design. This construction reduces the likelihood of breakout in the material into which the confirmat screw is driven. In practice, once installed, the confirmat ensures a secure joint that should not loosen even after a prolonged period.

How to use confirmat screws for furniture holes in chipboard (and more)?

Due to their specific construction, the process of joining two wooden components using a confirmat screw is slightly different from standard methods. It will be necessary to use a dedicated drill bit designed for confirmat fittings.

The assembly process and joining the two components requires both elements to be clamped simultaneously. Drilling should take place in a single operation. At the very end, remember to allow for a slight countersink. A slightly wider entry point makes it easier to drive the screw into the wood so that the screw head sits flush with the surface. However, care must also be taken to ensure the countersink is not too deep. If the top of the hole is widened excessively, the screw may sit at the incorrect depth.
