Hillman Fasteners 42478 Wood Screws 8x1.75 in 75 Pack

Product Description

The HILLMAN FASTENERS 42478 is a 75-pack of Number 8 by 1.75-inch all-purpose wood screws engineered for exterior applications. These flat-head fasteners feature a Type 17 cutting point that bores cleanly into wood without pre-drilling, and a special cross-cut thread design that reduces splitting and drive torque. The star drive recess delivers high bit engagement and minimizes cam-out. A bronze-colored 1,000-hour ceramic coat over yellow zinc plating provides corrosion resistance suited to outdoor and exposed installations. Carpenters, deck builders, and general contractors are the typical installers for this fastener type.

These screws are intended for exterior wood fastening tasks including decking, fencing, framing, and trim work. The all-purpose designation covers softwood and hardwood substrates where a flat-head profile is required to sit flush or countersink. The 1,000-hour ceramic coat rating indicates performance in salt-spray testing, making these appropriate for coastal and high-moisture environments. Each box contains 75 screws, and the product is packaged in units of 5 boxes per case.

Key Features

• Type 17 point cuts into wood fiber cleanly, reducing the need for pre-drilling
• Special cross-cut thread minimizes wood splitting and lowers drive torque
• Star drive recess provides high torque transfer and reduces cam-out
• 1,000-hour ceramic coat over yellow zinc for corrosion resistance in exterior conditions
• Flat head with nibs seats flush and cleans the countersink on installation
• 75 screws per pack for efficient job-site use

Compatibility

Designed for general exterior wood fastening applications including decking, fencing, and structural wood assemblies where a Number 8 flat-head screw with star drive is specified.

Installation Notes

Installation is performed with a star-drive bit sized to match the recess; use a variable-speed driver to control seating depth and avoid overdriving. For hardwood substrates or dense materials, a pilot hole may improve results even with the Type 17 point. Follow applicable building codes for fastener spacing and edge distances on structural and deck applications. Store unused screws in a dry location to preserve the ceramic coating.
