Simpson Strong-Tie Deck-Drive DWP Wood SS Screw

Simpson Strong-Tie is offering new load-rated sizes of the Deck-Drive DWP Wood screw in stainless steel. The fastener is designed for use in decks, docks, boardwalks and high-exposure environments that require exceptional corrosion resistance and higher loads.

Engineered to provide fast, easy installations, the DWP SS screw is an ideal solution for almost any exterior wood-to-wood fastening application and, now with larger load-rated sizes, it’s also recommended for structural connections.

The popular DWP screw has undergone rigorous testing per ICC-ES acceptance criteria AC233 for shear, pull-through and withdrawal resistance in various wood species (Douglas fir–larch, southern pine, spruce-pine-fir, hemlock-fir) in a range of thicknesses. (Please check for sizes, lengths and applicable loads.)

The new load-rated DWP SS screws are available in flat-head sizes #10, #12 and #14, and in lengths from 2 to 6 inches in Types 316 and 305 stainless steel.

“Simpson Strong-Tie is proud to lead the industry by offering the first load-rated stainless-steel fasteners that don’t require predrilling for use in decks, docks and boardwalks,” said Dr. Ed Sutt, VP of Fastening Systems at Simpson Strong-Tie. “Load-rated stainless-steel fasteners give builders, engineers and architects more confidence in the strength of the products they use and specify, along with the exceptional corrosion resistance of stainless steel.”
