Sheet to Heavy Section

Sheet to heavy section screws are robust self-drilling fixings for use with heavier gauge purlins, rails and primary steel framing. They are rated for steel thicknesses from 4.0mm up to 12.0mm and feature a heavy-duty #5 drill point with a fully threaded shank, available in lengths from 38mm to 76mm. This delivers strong penetration and secure thread engagement in thicker materials, making them ideal for applications requiring higher load capacity. The self-drilling action still allows efficient installation while providing dependable long-term fixing performance in more substantial steel frameworks within roofing and cladding systems.
