The HILLMAN FASTENERS 48440 is a 5-pound box of Deck Plus Gray Ceramic exterior composite deck screws sized at 2.5 inches by number 10. These screws are engineered for outdoor composite decking applications where corrosion resistance and holding strength are critical. The gray ceramic coating provides a 1500-hour salt spray rating, making them suitable for coastal and high-humidity environments. A self-drilling cut point eliminates pre-drilling in most composite materials, and the dual-thread design improves pull-through resistance and reduces surface mushrooming around the fastener head. Installation is handled by deck builders, carpenters, and general contractors working on exterior composite deck systems.
These screws are designed for exterior composite decking installations in both residential and light commercial settings. The star drive recess reduces cam-out during installation, which is especially useful when driving large quantities in production framing or deck construction. The gray ceramic finish is selected to blend with common composite deck board colorways. Each box contains 5 pounds of fasteners, packaged in a case quantity of 4 boxes per carton. They are intended for above-grade exterior applications where long-term corrosion resistance is required.
Designed as an OEM-style exterior fastener for use with composite deck boards in above-grade outdoor construction applications.
Installation is typically performed by carpenters or deck contractors using a power driver with a star drive bit. Ensure the composite decking material is properly supported and spaced per the deck board manufacturer requirements before fastening. Power down any adjacent electrical systems if working near exterior wiring runs. Follow local building codes and the composite decking manufacturer guidelines for fastener spacing and edge distance.
