Hillman Fasteners 117937 Roofing Screw 10x1.5 White Zxl

Product Description

The HILLMAN FASTENERS 117937 is a ZXL Premium metal-to-wood self-drilling roofing screw sized 10 x 1.5 inches, finished in white for use on color-matched steel roofing panels. The screw features a molded diecast Zamac 3 zinc-aluminum alloy head washer that provides lifetime protection against red rust. A 2.5-mil powder coat with chromate sealer delivers enhanced corrosion resistance over painted heads. Thread geometry transitions from fine to coarse along the shank to generate superior holding strength across various wood substrates. A Pro-Stick bit is included. This fastener is installed by roofing contractors, metal building erectors, and post-frame construction crews.

This screw is designed to fasten steel roofing panels to wood purlins in post-frame construction and to plywood or OSB decking in residential construction. The micro bit point minimizes metal shavings that could embed in the rubber washer, keeping the seal intact after installation. The geometry allows the screw to start fast and drive straight, reducing rework on large-panel roofing jobs. Each purchase covers a 5-box pack.

Installation Notes

Installation is performed by licensed roofing contractors or metal building crews following applicable building codes. Drive screws with a variable-speed drill or impact driver set to a controlled torque to avoid over-driving and compressing the rubber washer excessively. Inspect the washer seat after driving to confirm a proper weather seal. Use the included Pro-Stick bit to maintain straight drive alignment across corrugated and standing-seam panels.
