Wood screw 4x40mm, TH20 countersunk head yellow Zn KAMFIX

KAMFIX professional wood screws with a countersunk head and TX20 slot are a top-class fastening solution designed for the construction of structures subjected to intense mechanical stresses and loads. Thanks to its innovative engineering design, this model provides extremely high joint strength and long-term stability of the connected elements. The product features a precisely crafted countersunk head that allows for completely smooth sinking into the wood, ensuring a flawless and aesthetically pleasing finish to the installation work, without compromising the integrity of the surrounding surface.

The screws are equipped with a modern TORX slot (star), which guarantees optimal power transmission from the tool and allows for significantly higher torque during work, without the need to exert strong pressure. The specially developed "type 17" tip acts as a self-tapping drill, which cuts the wood fibers and prevents annoying cracking and splitting of the material, even when working in close proximity to edges. The additional ribs after the screw line and the interrupted thread geometry drastically reduce friction, which makes screwing easier, protects the battery of cordless tools and saves time on the site.

Purpose:

• For building large wooden structures, roofing systems, gazebos, sheds and pergolas
• For use in furniture production and the production of solid parts and interior elements
• For assembly and installation of wooden joinery, window shutters and exterior cladding
• For connecting soft and hardwood elements subjected to permanent structural stresses

Main advantages:

• Increased efficiency through the interrupted helix, which provides aggressive and smooth penetration into the workpiece
• Complete protection of the material from damage thanks to the cutting tip, which eliminates the risk of internal delamination in the wood
• Long service life of the assembly thanks to the yellow zinc coating, resistant to moisture and atmospheric corrosion
• Reduced load on the tools due to the special grooved part (ribs) that reduces resistance when screwing
• Maximum grip of the bit in the TX20 slot, preventing slippage and bit wear
• Possibility of combining with a specialized decorative washer to achieve a perfect designer look
