Stainless steel self drilling screw with reduced drilling point guarantees optimum tightness of the fastening

The stainless steel self-drilling screw manufactured in BIMETAL technology combines high mechanical strength with excellent corrosion resistance.
The case-hardened thread ensures high cutting performance and secure anchorage in the substrate, while maintaining a ductile core. This increases resistance to dynamic loads and reduces the risk of screw fracture.
The reduced drill point enables fast drilling start and precise screw guidance, minimizing the risk of slipping on the sheet surface and damage to the protective coating.

The thread extended up to the head prevents screw overdriving and ensures strong clamping of the connected elements. It allows installation without a sealing washer in applications where watertightness is not required.
The specially designed thread geometry and pitch enable stable and durable fastening of profiled sheets to each other, ensuring high load-bearing capacity of the joint.
The self-vulcanizing EPDM sealing washer is resistant to UV radiation, ageing, and temperature fluctuations. It guarantees long-term watertightness and protects the joint against water ingress.

The screw is intended for outdoor applications and maintains its performance in environments with elevated humidity and significant temperature variations.
