WKCS screws are designed for connecting wooden and wood-based elements (chipboard, plywood, wood, OSB, MDF). Their innovative design makes working with them a pure pleasure. They do not require pre-drilling.

The deep and stable TORX socket effectively transfers torque without the "bit popping out" effect.

Features and Benefits

1.) Countersunk head with TX socket

• The countersunk head ensures proper countersink and flush fit in the fastened element

• The deep TX socket guarantees optimal torque transfer without the "bit popping out" effect

2.) Cutting projections

• Thanks to The notches make it easier for the screw head to sink, providing an aesthetically pleasing surface finish.

3.) Countersink Cutter

• Reduces the torque required for screwdriving by widening the hole in the fastened element.

4.) Cutting Notches

• Special cutting notches on the thread cut the fibers of the wood structure during screwdriving.

5.) Milling Tip

• The special shape of the milling tip provides 20% less resistance during screwdriving, which extends the life of the battery and the tools themselves.

6.) Double Thread

• Additional threads on the tip facilitate screwdriving - they allow for faster "gripping" of the wood with less pressure, without drilling a pilot hole.

7.) Wax coating

• A special wax coating applied during the manufacturing process reduces the torque when screwing in the screw. This makes installation faster and easier, and consumes less energy, which is important in battery-powered tools.

8.) High Torque

• Allows you to drive screws without pre-drilling in hard types of wood.

New shape of the milling tip

The innovative change in the screw's design is designed to further improve its mounting properties.

• even faster installation,

• less resistance,

• greater battery savings (more screws driven on a single charge)

• reliable durability.

The auction includes two types of screw models (with the old and new shank). Due to the fact that the manufacturer still supplies us with two types of screw models, we cannot guarantee that you will receive the screw with the desired shank.

Double thread - faster installation

Additional threads on the tip allow for faster "grabbing" of the wood in the first stage of screwing. This advantage is particularly important in the case of connections where tightening the screw is difficult. The double thread allows us to achieve the same effect with much less pressure.

Up to 40% faster screwdriving time

In tests conducted before the product was implemented, we confirmed that the new shape of the screw tip shortens the screwdriving time by up to 40% under the same load. Savings depend on the type of joint and wood used.

1. Old tip

2. New tip

Up to 20% less resistance when screwing

The new shape of the milling tip reduces resistance when screwing by up to 20%. This parameter is particularly important for those specialists who use cordless tools on a daily basis - it extends the battery life.

a.) Screwdriving resistance Nm,

b.) Depth anchorage,

1.) Old tip,

2.) New tip.

High strength parameters

The new tip of carpentry screws, designed in cooperation with contractors, facilitates installation and is characterized by high strength parameters such as: pull-out strength, shear strength, etc.

a.) Pull-out strength, kN

1.) Old tip,

2.) New tip.

1. Connecting structural beams at an angle,

2. Connecting beams in a wooden pergola structure,

3. Construction of a roof truss,

4. Connecting rafters to a wall plate,

5. Fixing battens and counterbattens,

6. Mounting boards to a wooden structure

7. Mounting boards to a wooden structure

8. Mounting garden furniture

Additionally, these screws They are perfect for a variety of applications in wooden elements, including structures made of solid wood, glued laminated wood, or wood-like panels.

It's worth adding that, depending on their size, these screws may have different properties:

• Thicker screws have higher shear strength,

• Screws with a larger threaded surface offer better pull-out resistance.

The length of structural screws depends on the thickness of the elements being connected. The key to installing carpentry screws is that the entire threaded surface is embedded in the underlying material. Importantly, the screw tip should not penetrate the material.

Carpentry screws are dedicated to joining wood and wood-based materials. Currently, more and more new investments are being made using CLT, LVL, KVH, and BSH wood. The use of carpentry screws in them will increase the economy and ergonomics of work.

Carpentry screws are also dedicated to joining wood with materials such as plywood, chipboard, fiberboard, OSB, and particleboard-cement. Carpentry screws are products that require careful calculation.

Their proper placement and quantity impact the safety of the structure. During design and selection, their arrangement, the type of load they are subjected to and the forces acting on the screws should be taken into account, i.e.

pulling the head through the fastened element, pulling the carpentry screw out of the structure by a tensile force or a shear force that may break the connection.

1. Solid wood

2. Glued solid wood (CLT, KVH, BSH/GLT, LVL)

3. Wood-like boards (OSB, MDF, plywood, chipboard)

Carpentry screws are becoming more and more popular, replacing traditional nails thanks to their many advantages:

• ability to carry significant loads,

• easiness and speed of installation,

• precise connection of screwed elements,

• improvement of the rigidity of the entire structure,

• enable easy corrections during installation - in the event of an error during installation, the screw can be easily unscrewed and screwed back in.

1. Only original screws supplied by the manufacturer may be used.

2. Before starting the installation, select the appropriate length. screws depending on the thickness of the elements being fastened and the minimum anchorage depth. The wooden elements being connected should be free from defects (knots, cracks, discoloration, rot, mechanical damage), as this reduces their strength.

The screws should be installed using a screwdriver and a suitable TX-type bit. The screws can be screwed directly into the wooden substrate without pre-drilling holes or in pre-drilled holes, which reduces the risk of cracking small elements.

The diameter of the pre-drilled holes should not be larger than the internal diameter of the thread. The minimum spacing between screws and the distance from the edge should be observed. (declaration of performance)
