The special drill bit shape designed to provide quick and trouble-free installation in metal constructions made from cold formed sections

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.
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 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 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 optimised drill point geometry enables efficient drilling in steel, reducing installation time and increasing assembly efficiency
