Hillman Fasteners 48397 Deck Screw 1.625in X 8 Box of 12

Product Description

The HILLMAN FASTENERS 48397 is a Deck Plus Green Ceramic exterior screw designed for outdoor structural fastening applications. At 1.625 inches long and size 8, this screw features a self-drilling cut point that eliminates the need for pilot holes in most wood substrates. The green ceramic coating provides corrosion resistance rated to 1500 hours of salt spray testing, making it well-suited for pressure-treated lumber, deck boards, and other exterior wood assemblies. It drives with a star drive bit for reduced cam-out. The coarse, serrated thread pattern pulls materials tight and resists loosening over time. This fastener carries a lifetime warranty and comes packaged in a box of 12.

This screw is intended for exterior wood decking, framing, and general outdoor construction where corrosion resistance and holding power are critical. It is appropriate for use with pressure-treated lumber commonly found in residential and light commercial deck construction. Contractors, deck builders, and finish carpenters will find the self-drilling point and star drive pattern reduce installation time on large fastening jobs. The green ceramic coating is specifically engineered to resist the chemical environment created by modern ACQ and CA pressure-treated wood treatments.

Installation Notes

Installation is performed by carpentry and general construction trades using a star drive bit. Always use the correct star drive bit size to avoid stripping the recess. When fastening into dense hardwoods or composite materials, a pilot hole may still be recommended even with a self-drilling point. Follow local building codes and deck construction standards for fastener spacing and edge distances.
