Hillman Fasteners 117904 Roofing Screw 10x1 Inch Brown 5 Pack

Product Description

The HILLMAN FASTENERS 117904 is a No. 10 x 1 inch metal-to-wood self-drilling roofing screw with a Koko Brown powder coat finish. It is engineered to fasten steel roofing panels directly to wood purlins in post-frame construction, as well as to plywood or OSB decking in residential roofing applications. The hex washer head (HWH) features a V-neck design that adds structural strength and resists head pop-out under load. An EPDM rubber gasket is vulcanized to a steel washer, forming a weatherproof seal even when the screw is driven at a slight angle. Sold in a 5-count package with a Pro-Stick bit included.

These screws are suited for contractors and framers working on post-frame agricultural and commercial buildings, as well as residential roofers fastening steel panels over plywood or OSB substrates. The thread design transitions from fine to coarse along the shank, which improves holding strength across different wood densities. The Micro-Bit point minimizes metal shavings during penetration, reducing the risk of debris embedding in the EPDM washer and compromising the seal over time.

Key Features

• No. 10 x 1 inch self-drilling point drills through steel roofing and into wood substrate in a single pass
• EPDM rubber gasket vulcanized to a steel washer provides a weatherproof seal even at off-angle drives
• HWH with V-neck design increases head strength and resists pop-out
• 2.5 mils of powder coat with chromate sealer delivers enhanced corrosion resistance over painted heads
• Fine-to-coarse thread transition generates superior holding strength in varying wood substrates
• Micro-Bit point reduces metal shavings that could damage the rubber washer
• Pro-Stick driver bit included in each package

Compatibility

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

Installation Notes

Installation is typically performed by roofing contractors or framers using a hex-head driver or impact driver at controlled torque to avoid compressing the EPDM washer excessively. Do not overdrive — excessive torque will distort the rubber gasket and reduce the weatherproof seal. Follow applicable building codes and roofing manufacturer fastening patterns for screw spacing and edge distance. Verify that the substrate thickness is appropriate for the 1 inch screw length before installation.
