Hillman Fasteners 117919 Roofing Screw 10x1.5 Black 5 Pack

Product Description

The HILLMAN FASTENERS 117919 is a No. 10 x 1.5-inch self-drilling roofing screw engineered for metal-to-wood fastening applications in post frame and residential construction. The black powder-coated finish includes 2.5 mils of powder coat with a chromate sealer, delivering enhanced corrosion resistance compared to standard painted-head screws. The hex washer head features a V-neck design that adds clamping strength and resists head pop-out under load. An 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 Pro-Stick driver bit is included. Sold in a box of 5 units.

These screws are designed to fasten corrugated or ribbed steel roofing panels to wood purlins in post frame construction and to plywood or OSB decking in conventional residential roofing applications. The dual-thread pattern transitions from fine threads near the tip to coarse threads in the shank, optimizing pull-out resistance across varying wood substrates. The micro-bit point is engineered to minimize metal shavings during drilling, reducing the risk of debris embedding in the EPDM washer and compromising the seal.

Key Features

• No. 10 x 1.5-inch self-drilling point drives through steel roofing into wood substrate without pre-drilling
• 2.5 mils powder coat with chromate sealer for enhanced corrosion resistance over painted-head alternatives
• EPDM rubber vulcanized to steel washer creates a weathertight seal even at off-angle drives
• HWH V-neck head design adds structural strength and prevents head pop-out
• Fine-to-coarse thread transition generates superior holding strength in wood purlins, plywood, and OSB
• Micro-bit point reduces metal shavings that could contaminate the rubber washer seal
• 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 sheathing in residential roofing applications.

Installation Notes

Installation is performed by roofing contractors and general carpenters using a hex-drive power drill or impact driver. Drive screws straight and at consistent depth to ensure the EPDM washer seats flush without over-compression. Follow applicable local building codes for fastener spacing and pattern requirements on metal roofing panels. Avoid over-driving, which can deform the rubber washer and reduce seal effectiveness.
