Hillman Fasteners 117905 Roofing Screw 10x1 Inch Antique Brown

Product Description

The HILLMAN FASTENERS 117905 is a self-drilling metal-to-wood roofing screw designed to fasten steel roofing panels directly to wood purlins and structural substrates. Sized at No. 10 x 1 inch with an antique brown finish, this screw is engineered for post frame construction and residential roofing applications. The hex washer head (HWH) features a V-neck design that adds shear strength and resists head pop-out under load. An EPDM rubber washer is vulcanized to a steel backing washer, forming a weathertight seal even when the fastener is driven at a slight angle. Threads transition from fine to coarse along the shank to maximize pullout resistance across varying wood densities. Each package includes a Pro-Stick driver bit.

These screws are suited for attaching corrugated or standing-seam steel roofing to wood purlins in post frame barns, agricultural buildings, and light commercial structures. They also perform in residential construction where plywood or OSB roof decking is used. The antique brown powder coat finish blends with common dark metal roofing panels. The enhanced corrosion-resistant coating consists of 2.5 mils of powder with a chromate sealer applied over the head, providing improved longevity in exposed outdoor installations. This product is sold as a box containing 5 units.

Key Features

• Self-drilling micro-bit point starts fast, drives straight, and minimizes metal shavings that could damage the EPDM washer seal
• EPDM rubber vulcanized to a steel washer forms a reliable weathertight seal even at off-angle drives
• HWH with V-neck design increases head strength and prevents pop-out under panel movement or wind load
• Thread profile transitions from fine to coarse for superior holding strength in purlins, plywood, and OSB
• 2.5 mils of powder coat with chromate sealer delivers enhanced corrosion resistance over painted heads
• Pro-Stick driver bit included in each box

Compatibility

Designed as an OEM-style replacement and standard-use fastener for steel roofing applications secured to wood substrates, including purlins in post frame construction and plywood or OSB decking in residential roofing systems.

Installation Notes

Installation is typically performed by roofing contractors or general construction crews using a hex-head power driver or impact driver. Confirm substrate thickness is sufficient for full thread engagement before specifying screw length. Drive screws to snug, not overtorqued, to avoid compressing the EPDM washer beyond its designed seating point. Follow applicable building code requirements for fastener spacing and edge distance on metal roofing panels.
