#10 x 3" 316 Marine Grade Stainless Steel Deck Screws

316 marine grade stainless steel deck screws - the highest corrosion resistance of any common fastener material. This is the grade for salt spray and coastal air, tidal or brackish water, pool and spa decks where chlorine is in play, and anything sitting permanently in or over water. Our 304 grade may discolor over time, but will never corrode or stain on your deck either, and it costs less. Where salt and chlorine never let up, 316 is simply the better screw.

Built for floating docks, jetties, boardwalks and seaside decking. The threadless upper shank pulls boards down tight and stops jacking, holding firmly in timber and composite decking alike, and works as an exterior wood screw for fencing, pergolas and outdoor furniture.
