Hillman Fasteners 117906 Roofing Screw 10x1 in White 5-pack

Product Description

The HILLMAN FASTENERS 117906 is a self-drilling metal-to-wood roofing screw designed to fasten steel roofing panels to wood substrates in both post frame and residential construction. Sized at No. 10 by 1 inch with a polished white finish, these screws feature a hex washer head (HWH) with a V-neck design that adds structural strength and resists head pop-out. The coating system applies 2.5 mils of powder with a chromate sealer, delivering enhanced corrosion resistance beyond standard painted heads. Each screw includes a vulcanized EPDM rubber washer bonded to a steel washer for a reliable weatherproof seal, even when driven at a slight angle. Sold as a box of 5 with a Pro-Stick bit included.

These screws are suited for attaching corrugated or ribbed steel roofing to wood purlins in post frame agricultural or commercial buildings, and to plywood or OSB decking in residential roofing applications. The thread profile transitions from fine to coarse along the shank to maximize holding strength across varying wood densities and substrates. The micro-bit point is engineered to start fast, drive straight, and minimize metal shavings that could otherwise embed in the rubber washer and compromise the seal.

Key Features

• Self-drilling point starts fast and finishes straight without pre-drilling
• Micro-bit point reduces metal shavings that can damage the EPDM washer seal
• EPDM rubber vulcanized to a steel washer forms a weatherproof seal even at an angle
• Fine-to-coarse thread transition generates superior holding strength in wood purlins, plywood, and OSB
• HWH with V-neck design resists head pop-out under load
• 2.5-mil powder coat with chromate sealer provides enhanced corrosion resistance over painted heads
• Pro-Stick driver bit included in each box

Compatibility

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

Installation Notes

Installation is typically performed by roofing contractors or general carpenters using a power drill or impact driver set to a controlled clutch depth to avoid over-driving and compressing the EPDM washer. Power down all adjacent electrical equipment and follow applicable fall-protection requirements before working on any roof surface. Do not over-torque — excessive drive depth will deform the rubber washer and reduce seal effectiveness. Use the included Pro-Stick bit for best alignment and drive consistency.
