⁵⁄₁₆” Hex Head 12G Metal-to-Wood Roofing Screw (1″~4″)

Hex Head Self-Drilling Roofing Screw Metal-to-Wood

12g Hex Head Roofing Screw – Watertight Seal and High Strength for Metal to Wood Fastening

This 12 Gauge Hex Head Self-Drilling Roofing Screw is an essential, specialized fastener for securing metal panels to wooden structures. The 12 Gauge diameter provides superior strength and high pull-out resistance, vital for high-wind and heavy-load applications.

The key feature is the Hex Head with an integrated bonded neoprene washer. As the screw is driven, the neoprene compresses against the metal panel, creating a reliable, watertight seal around the fastener hole, effectively preventing leaks and inhibiting corrosion beneath the screw head. The sharp, self-drilling point and aggressive coarse thread are optimized for fast penetration through the metal and secure, high-strength tapping into the wood framing beneath.

Key Benefits

• Watertight Seal: Bonded neoprene washer compresses to seal the screw hole, preventing water ingress and rust.

• Heavy-Duty 12 Gauge: Offers maximum pull-out strength and resistance to shear forces in exterior applications.

• Self-Drilling/Tapping: Sharp point allows for fast penetration through metal and secure tapping directly into wood without pre-drilling.

• Corrosion Resistance: Plated finish protects the steel from exterior elements, enhancing longevity.

• Easy Driving: Hex head design allows for high-torque driving using standard hex socket drivers.

Perfect For

• Installing metal roofing on residential, commercial, or agricultural buildings.

• Fastening metal siding or cladding panels to wooden walls and frames.

• Applications requiring a guaranteed watertight seal at the fastening point.

• General outdoor metal-to-wood construction.

Application Instructions

• Driving: Use a variable speed drill equipped with a ⁵⁄₁₆” hex driver bit (socket).

• Setting: Drive the screw straight through the metal panel and into the wood purlin/framing.

• Tightening: Stop driving when the neoprene washer is visibly compressed and sealed against the metal 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.

• For the longest service life, avoid crushing the neoprene washer, as this will lead to premature failure of the seal.

• Check the overall screw length to ensure adequate penetration into the wood framing (minimum 1 inch).

• Use the correct size hex driver bit to prevent stripping the head.
