Hillman Fasteners 42472 Wood Screw 9x2.5 in Star Drive 50 Pack

Product Description

The HILLMAN FASTENERS 42472 is a 50-pack of Number 9 by 2.5-inch yellow zinc all-purpose wood screws designed for interior fastening applications. Each screw features a flat head with nibs, a Type 17 point for self-starting penetration into wood, a special cross-cut thread pattern for reduced splitting and improved holding strength, and a star drive recess for positive bit engagement. The yellow zinc coating provides corrosion resistance appropriate for interior use. Licensed contractors, carpenters, and general tradespeople working on interior framing, trim, cabinetry, and structural wood assemblies will find these a reliable general-purpose fastener.

These screws are suited for interior wood-to-wood fastening in residential and light commercial construction. Typical applications include subfloor decking, interior framing, wood trim installation, cabinet assembly, and general carpentry work. The flat head with nibs seats flush and counters cleanly into wood substrates. The Type 17 auger point and cross-cut thread are engineered to reduce torque and minimize wood splitting, making them appropriate for hardwood and softwood applications alike.

Installation Notes

Installation is performed by carpenters, general contractors, or qualified tradespeople using a star drive bit and impact driver or drill. Confirm the correct bit size for the star drive recess before driving to avoid stripping. For hardwood applications, pilot holes are recommended to prevent splitting. These screws are rated for interior use only and should not be substituted in exterior or treated-lumber applications without verifying coating compatibility.
