You've spent all that money on quality decking products, why use fasteners that aren't designed to last the lifetime of the deck? Conquest 316 stainless deck screws are the high quality, corrosion resistant deck screws designed for severe corrosive environments like ocean side applications. This package of 350 installs 100 sq. ft. of decking for standard 6" wide boards and 16" joist spacing. The flat head version of our deck screws features a 6-lobe star drive for a positive engagement and no stripped screw heads. A type 17 point and serrated point threads make installation easy and preserve battery life on your cordless drill or impact driver. Screws 2" and greater feature shank ribs that enlarge the driving hole which reduces installation resistance, reduces splitting and enables the screw to draw the deck board tighter to the joist.
