Hillman Fasteners 116815 Flat Head Star Drive Screw 10 Pack

Product Description

The HILLMAN FASTENERS 116815 is a multi-material exterior screw designed for demanding installation environments. Part of the PowerPro One line, this flat head, star drive fastener measures 1/4 inch in diameter by 3.5 inches in length and carries a bronze epoxy premium coating for corrosion resistance in exterior applications. Each pack contains 10 screws. Licensed tradespeople and experienced installers use this fastener for structural and finish work where a single screw must perform reliably across multiple substrate types without corroding or backing out over time.

This screw is rated for use on wood, masonry, drywall, and plastic, making it a practical choice for mixed-substrate assemblies common in residential and light commercial construction. The flat head profile sits flush with the surface after seating, and the star drive recess provides positive bit engagement that reduces cam-out during installation. Typical applications include decking, framing connections, exterior trim, and masonry anchoring where a corrosion-resistant fastener is required.

Installation Notes

Installation should be performed by a qualified carpenter, contractor, or trades professional familiar with fastener selection for exterior applications. Pre-drilling a pilot hole is recommended when driving into hardwood or masonry to prevent substrate splitting and ensure proper seating depth. Use the correct star drive bit size to avoid stripping the recess. Follow applicable building codes, including IRC or IBC guidelines, for fastener schedules in structural applications.
