Deck Plus exterior deck screws offer a comprehensive finishing fastener solution, including exterior wood, composite, and trim uses. Deck Plus requires no pre-drilling and is perfect for all of your decking, fencing and exterior wood project needs. Engineered with no-strip star drive technology, these screws are twice as durable as comparable Philips-drive alternatives. Countersinking nibs under the head of the screw cut a perfect finished hole by transporting wood fibers out and sealing the surface. Serrated threading reduces drive torque. The brown ceramic coating provides superior rust and corrosion resistance with 4 layers of protection - a zinc layer, a chemical adhesion layer, an epoxy coating, and a durable protective finish. This coating protects against weather as well as corrosion due to chemicals found in treated lumber. The 4-layer coating also exceeds 1,000 hours in salt spray testing.
