Hillman Fasteners 117907 Black Roofing Screw 10x1 Inch 5 Pack

Product Description

The HILLMAN FASTENERS 117907 is a No. 10 x 1 inch black-finish self-drilling roofing screw engineered for metal-to-wood fastening applications. The screw features a hex washer head (HWH) with a V-neck design that adds shear strength and resists head pop-up under load. A 2.5 mil powder coat with chromate sealer delivers enhanced corrosion resistance compared to standard painted heads. The integrated EPDM rubber washer is vulcanized directly to a steel backing washer, forming a weathertight seal even when the fastener is driven slightly off-angle. A micro-bit point minimizes metal shavings during penetration, protecting the rubber washer from damage. Each box contains 5 screws and includes a Pro-Stick driver bit.

This screw is designed for fastening corrugated or ribbed steel roofing panels to wood purlins in post-frame and agricultural construction, as well as to plywood or OSB decking in residential roofing applications. The thread profile transitions from fine to coarse along the shank, optimizing holding strength across varying wood substrate densities including engineered panels and dimensional lumber.

Key Features

• Self-drilling tip starts fast and drives straight without pre-drilling in most wood substrates
• Micro-bit point reduces metal shavings that could embed in and degrade the EPDM washer
• Thread transitions from fine to coarse for superior holding strength in wood and engineered panels
• 2.5 mil powder coat with chromate sealer provides enhanced corrosion resistance over painted-head alternatives
• EPDM rubber vulcanized to steel washer creates a reliable weathertight seal even at slight drive angles
• HWH with V-neck design adds head strength and prevents pop-through under uplift loads

Compatibility

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

Installation Notes

Installation is typically performed by roofing contractors or general construction crews using a hex-head driver bit — a Pro-Stick bit is included in each box. Drive screws to snug, not overtorqued; excessive torque will compress and distort the EPDM washer, compromising the seal. Follow applicable building codes for fastener spacing and edge distance when attaching metal roofing panels. Inspect driven fasteners to confirm the rubber washer is seated flush and undistorted at the panel surface.
