Forgefix TechFast Hex Head Roofing Screws are designed for fixing cladding and sheet steel to light section steel purlins. They feature a self-drilling tip that enables installation without pre-drilling, and a rubber washer that compresses to form a permanent weather seal. The screws are treated with an Elementech multi-layer coating for corrosion resistance and are zinc plated. Salt spray testing confirms durability in outdoor environments.
