Description

Painted Purlin Screws Gunmetal 1″ (100 pcs) 1″ Gunmetal Painted Purlin Screws – Watertight Seal and Color-Matched Durability for Roofing These 1″ Gunmetal Painted Purlin Screws are specialized, essential fasteners for professional metal roofing and siding applications. The 1-inch length is ideal for fastening single metal sheets securely to wood or light-gauge steel purlins, providing a strong hold with minimal excess length. Highlight the core feature: the Gunmetal Painted Hex Head is color-matched to blend seamlessly with dark grey/charcoal roofing panels, providing a clean, finished aesthetic. The integrated bonded neoprene washer compresses during driving to create a durable, watertight seal around the screw hole, effectively preventing leaks and inhibiting corrosion. The Self-Drilling (Tek) Tip eliminates the need for pre-drilling through the metal sheet, greatly accelerating installation. Supplied in a convenient 100-piece box, they are ready for high-volume use. Key Benefits Color-Matched Aesthetic: Gunmetal painted heads blend seamlessly with dark metal roofing/siding panels. Watertight Seal: Bonded neoprene washer compresses to seal the screw hole, preventing water ingress and rust. Self-Drilling Efficiency: Tek tip drills its own pilot hole through metal, accelerating installation (no pre-drilling). Corrosion Resistance: Plated shank and painted head offer double protection against exterior weather elements. Ideal Short Length: 1″ length is perfect for single-sheet fastening to purlins or for lap joints.

Application Instructions Driving: Use a variable speed drill equipped with a correct size hex driver bit (socket). Setting: Drive the screw straight through the panel and into the purlin. Tightening: Stop driving immediately when the neoprene washer is visibly compressed and sealed against the panel. Do not over-tighten or crush the neoprene. Safety: Wear safety glasses during installation. Pro Tips Always drive the screw perpendicular to the panel to ensure the washer seats correctly and prevents leaks. Do not over-tighten, as crushing the neoprene will cause the seal to fail prematurely. Clean off any metal shavings immediately after drilling to prevent rust spots on the panel. Ensure the color of the painted head matches the metal panel you are installing for a seamless aesthetic.
