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.
