The HILLMAN FASTENERS 42591 is a 75-count pack of Deck Plus exterior screws designed for outdoor decking and structural fastening applications. Each screw measures 1-5/8 inches in length and is a size 8 diameter, featuring a tan ceramic coating engineered to resist corrosion in exposed exterior conditions. The self-drilling cut point eliminates the need for pre-drilling in most softwood decking materials, speeding up installation. Coarse, serrated threads provide strong pull-through resistance and a secure bite into wood. These screws carry a 1,500-hour salt spray rating and a lifetime warranty, making them a reliable choice for coastal or high-moisture environments.
These screws are suited for residential and light commercial deck construction, including decking boards, railings, and exterior wood framing. The tan ceramic finish is intended to blend with common pressure-treated and composite decking tones. Carpenters, general contractors, and experienced DIYers working on outdoor structures will find the self-drilling tip and serrated thread profile well suited to production fastening work where speed and holding strength both matter.
Designed as an OEM-style exterior fastener for use with standard wood and pressure-treated decking boards in residential and light commercial deck construction.
Installation should be performed by a qualified carpenter or contractor following applicable local building codes for deck construction. Ensure the correct star drive bit is used to prevent cam-out and bit damage. When fastening near board edges or ends, a pilot hole is recommended to reduce splitting, even with the self-drilling tip. Use appropriate personal protective equipment including eye protection when driving fasteners at production speed.
