Hillman Fasteners 48399 Deck Plus Green Ceramic Screws

Product Description

The HILLMAN FASTENERS 48399 is a No. 8 by 2-inch exterior deck screw engineered for demanding outdoor fastening applications. These screws feature a green ceramic coating that passed 1500-hour salt spray testing, providing long-term corrosion resistance in exposed environments. The self-drilling cut point eliminates the need for pre-drilling in most applications, and the coarse, serrated thread pattern pulls material tight while reducing surface mushrooming. A star drive recess provides positive bit engagement and reduces cam-out during installation. Licensed contractors, deck builders, and remodelers rely on these fasteners for structural and finish decking work.

These screws are suited for fastening pressure-treated lumber, cedar, redwood, and composite decking to wood substructures in residential and light commercial exterior applications. The green ceramic finish is specifically matched to bleed-through concerns common with treated lumber. They are packaged in a box quantity of 12 pounds and are appropriate for both hand-drive and impact-driver installation in new-build and replacement decking projects.

Key Features

• Green ceramic coating rated to 1500-hour salt spray resistance for corrosion protection in exterior environments
• Self-drilling cut point reduces or eliminates the need for pilot holes in dimensional lumber
• Coarse, serrated thread pulls material together and minimizes surface lifting
• Star drive recess reduces cam-out and improves torque transfer with standard star bits
• Lifetime warranty per manufacturer

Compatibility

Designed for exterior deck construction and repair using pressure-treated lumber, cedar, redwood, and similar dimensional wood substrates where a corrosion-resistant exterior screw is required.

Installation Notes

Installation is performed by carpenters, deck contractors, or general contractors working under applicable building codes. Power down or disconnect any live electrical circuits near the work area before fastening near utility penetrations. Use a star-tip driver bit matched to the drive size to avoid stripping the recess. Follow local building codes for fastener spacing, edge distance, and load requirements on structural deck assemblies.
