Features

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.
