Hillman Fasteners 117521 Roofing Screws 10x1.5 in 250pc Red

Product Description

The HILLMAN FASTENERS 117521 is a 250-piece contractor pack of WB Premium Metal to Wood Roofing Screws in red, sized 10 x 1.5 inches. These fasteners are engineered to secure steel roofing panels to wood substrates in demanding construction environments. The head and washer assembly uses molded diecast Zamac 3 zinc aluminum alloy, which provides lifetime protection against red rust. Corrosion resistance is further enhanced with 2.5 mils of powder coating plus a chromate sealer over the painted heads. Each pack includes a Pro-Stick bit for consistent driver engagement. Backed by a 40-year warranty, this contractor pack is suited for high-volume roofing work.

These screws are designed for fastening steel roofing to wood purlins in post-frame construction and for attaching plywood or OSB in residential roofing applications. The micro-bit point is engineered to minimize metal shavings during penetration, reducing the risk of debris embedding in the rubber washer seal. This makes them a practical choice for metal roofing installers and framing contractors working on agricultural buildings, commercial post-frame structures, and residential re-roof or new construction projects where a reliable weather-tight fastener is required.

Installation Notes

Installation is performed by roofing contractors or framing carpenters using a power driver or impact driver with the included Pro-Stick bit. Follow local building codes and roofing manufacturer guidelines for fastener spacing and penetration depth. Do not overdrive screws, as compressing the rubber washer beyond its designed range can compromise the weather seal. Inspect the washer seating on each fastener after installation to confirm proper compression.
