Hillman Fasteners 117940 Roofing Screw 10x1.5 Antique Brown 5-pack

Product Description

The HILLMAN FASTENERS 117940 is a ZXL Premium self-drilling metal-to-wood roofing screw in Antique Brown, sized 10 x 1.5 inches. It is engineered to fasten steel roofing panels directly to wood substrates without pre-drilling. The corrosion-resistant coating system combines 2.5 mils of powder coat with a chromate sealer and a molded diecast Zamac 3 zinc-aluminum alloy head washer that provides lifetime protection against red rust. The thread design transitions from fine to coarse, generating strong holding power across different wood substrates. A micro bit point limits metal shaving production that could embed in the rubber washer. Each box includes a Pro-Stick bit. This item ships as a 5-box pack. Licensed HVAC technicians, roofing contractors, and post-frame construction crews are the primary installers.

These screws are designed for two primary applications: fastening steel roofing panels to wood purlins in post-frame and agricultural construction, and securing plywood or OSB sheathing in residential roofing assemblies. The Antique Brown finish is matched to common painted metal roofing panel colors to maintain a clean, consistent appearance on finished roofs. The self-drilling point eliminates the need for a pilot hole in typical light-gauge steel and wood substrates, speeding up installation on large roof surfaces.

Compatibility

Designed for metal-to-wood roofing applications fastening steel roofing panels to wood purlins in post-frame construction and to plywood or OSB decking in residential construction.

Installation Notes

Installation is performed by roofing contractors or post-frame construction crews. Shut down any powered equipment in the work area and follow applicable fall-protection requirements before working on roof surfaces. Drive screws to proper seating so the rubber washer compresses evenly without over-driving, which can compromise the weather seal. Do not substitute a standard drill bit for the included Pro-Stick bit, as proper bit engagement reduces cam-out and keeps the screw driving straight.
