Features

Stainless steel self drilling screw with the special drill bit shape designed to provide quick and trouble-free installation in metal constructions made from cold formed sections

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 optimised thread geometry and pitch ensure fast penetration into the steel substrate and provide high load-bearing capacity of the joint.

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.
The optimised drill point geometry enables efficient drilling in steel, reducing installation time and increasing assembly efficiency
Screws available with a coloured polyester coating (RAL) provide additional corrosion protection and ensure aesthetic matching with roofing or façade cladding. UV stabilisers guarantee long-term colour durability and resistance to fading throughout the service life.
