The HILLMAN FASTENERS 48401 is a green ceramic-coated exterior deck screw designed for outdoor structural fastening applications. Measuring 2.5 inches in length and sized at number 10, these screws feature a self-drilling cut point that eliminates the need for pre-drilling in most softwood decking. The coarse, serrated thread pattern drives fast and bites securely into wood framing and decking material. The green ceramic coating is rated to 1500 hours of salt spray resistance, making these fasteners suitable for treated lumber, coastal environments, and other corrosive exterior conditions. Licensed trades and experienced DIYers use these screws for deck boards, exterior trim, and similar above-ground wood assemblies.
These screws are packaged in a box quantity of 12 pounds and are intended for residential and light commercial exterior woodworking applications. The star drive head reduces cam-out during installation, which is especially useful in repetitive fastening tasks on decking projects. The self-drilling point and serrated threads are optimized for softwood and pressure-treated lumber. The lifetime warranty reflects the durability expectation for a ceramic-coated exterior fastener in demanding outdoor environments.
Designed for use with pressure-treated lumber, composite decking substructures, and exterior softwood assemblies where a corrosion-resistant fastener is required.
Installation is typically performed by carpenters, deck builders, or general contractors using a power drill or impact driver fitted with a star drive bit. Ensure the correct bit size is used to avoid stripping the drive recess. When fastening into pressure-treated lumber, always follow current building code requirements for corrosion-resistant fasteners. Power down all adjacent electrical runs and follow standard jobsite safety protocols before beginning fastening work near utility penetrations.
