Features

Special zinc flake corrosion-resistant coating for highly effective protection

Hardened screw's thread surface. High quality anti-corrosion coating guarantees resistance of 15 Kesternich cycles.
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 shape of the thread and its height is designed for applications into sandwich panels and steel construction.

Two types of threads: one designed for mounting into a steel structure, second under head thread, prevents external panel dents and helps to seal the connection.
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.
Special zinc flake corrosion-resistant coating for anti-corrosion protection.

Drilling point - especially approach angle of self-drilling tip allows direct installation without predrilling up to 18mm.
