49325 Deck Screw, #10 Thread, 2-1/2 in L, Serrated Thread, Flat Head, Phillips Drive, Self-Drilling Point

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 ideal 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 Phillips-drive alternatives. Countersinking nibs under the head of the screw cut a well finished hole by transporting wood fibers out and sealing the surface. Serrated threading reduces drive torque. The brown ceramic coating provides good rust and corrosion-resistance with four 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 four-layer coating also exceeds 1000 hr in salt spray testing.
