Features

Reduced drilling point guarantees optimum tightness of the fastening

• 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 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.
