Hillman Fasteners 117441 Roofing Screw 10x1 250pc

Product Description

The HILLMAN FASTENERS 117441 is a self-drilling metal-to-wood roofing screw designed for fastening steel roofing panels and sheet metal to wood substrates. Sized at No. 10 x 1 inch, this screw features a hex washer head (HWH) with a V-neck design that adds mechanical strength and reduces the risk of head pop-out under load. The EPDM rubber washer is vulcanized directly to a steel washer, forming a weathertight seal even when the fastener is driven at a slight angle. A 2.5-mil powder coat with chromate sealer over a charcoal gray painted head delivers enhanced corrosion resistance. Each contractor pack contains 250 screws and includes a Pro-Stick bit for faster driving. These are backed by a 40-year warranty.

These screws are intended for post-frame construction where steel roofing or cladding attaches to wood purlins, and for residential construction applications involving plywood or OSB decking. The micro-bit point is engineered to self-drill through steel roofing material into wood framing with minimal metal shaving generation, which protects the rubber washer from debris damage during installation. The charcoal gray finish coordinates with common steel panel colors used in agricultural and residential metal roofing systems.

Installation Notes

Installation is performed by roofing contractors and general carpenters using a hex-drive bit and a variable-speed screw gun or impact driver. Use the included Pro-Stick bit to maintain alignment and consistent drive depth. Avoid over-driving, which can compress or shear the EPDM washer and compromise the seal. Follow local building codes and panel manufacturer fastening schedules for spacing and edge-distance requirements.
