Hillman Fasteners 117935 Roofing Screw 10x1.5 Grey 5 Pack

Product Description

The HILLMAN FASTENERS 117935 is a ZXL Premium Metal to Wood self-drilling roofing screw sized at number 10 by 1.5 inches, finished in grey. It is engineered for fastening steel roofing panels directly to wood substrates without pre-drilling. The Dura Seal coating system applies 2.5 mils of powder with a chromate sealer over the shank, while the head and washer seat are formed from molded diecast Zamac 3 zinc-aluminum alloy, providing lifetime protection against red rust. A micro bit point minimizes metal shavings that could embed in the rubber washer. Each package includes a Pro-Stick bit and carries a 40-year warranty.

This screw is intended for steel roofing applications in two primary scenarios: fastening metal roof panels to wood purlins in post-frame construction, and fastening metal roofing over plywood or OSB sheathing in residential construction. The thread profile transitions from fine to coarse along the shank, which generates strong holding force across varying wood densities and substrates. The grey finish is color-matched for use with grey steel roofing panels. Each unit of measure is sold as a package of 5 screws.

Installation Notes

Installation is typically performed by roofing contractors or general construction tradespeople. Ensure the roof deck or purlin is clear of debris and properly aligned before driving screws. Use the included Pro-Stick bit and a variable-speed drill or impact driver set to avoid overdriving, which can compress or damage the rubber washer seal. Follow applicable building codes for fastener spacing and penetration depth requirements in your jurisdiction.
