Simpson Strong-Tie SDWS Stainless Steel Timber Screws are built for your toughest outdoor wood projects, especially in areas exposed to moisture, salt, or chemicals. Whether you're framing a deck by the coast, assembling landscape timbers, or working on a backyard structure, these screws offer unmatched corrosion resistance and structural strength.

Made from 316 stainless steel, they stand up to the harshest conditions without rusting or degrading over time. The screw’s patented tip drives fast and clean into wood with no pre-drilling, while the large washer-style head provides consistent clamping force to keep materials tight and secure.
