Exterior Wood Screws

“Standard 1-inch screws rusted within months on our coastal deck projects. We used Sinsun's 1-inch stainless steel screws to hold down the composite decking. There is no corrosion or staining after two full seasons. We've gotten rid of all callbacks for popped or rusted fasteners, and the low-profile head always gives a perfect finish.”

"Building my backyard cedar planter boxes, I needed a 3-inch screw that wouldn't split the wood. Sinsun's exterior screws with the self-drilling tip were a game-changer. I drove over 200 of them without a single pilot hole or split. The project was done in one afternoon, and the boxes have held solid through two freeze-thaw cycles."

"The Australian sun and rain destroy inferior fasteners. For our 4-inch screws used in heavy fence posts and gate frames, Sinsun's triple-coated option is the only one that holds up. We get consistent depth with an impact driver, and the coating hasn't failed in three years of our toughest installations. It's now our standard spec."

"Restoring an old oak gazebo required 6-inch screws to replace rotten mortise-and-tenon joints. We needed immense strength without the bulk of bolts. These screws had the sheer strength we needed (tested over 1,800 lbs), and the long drill point made driving them into century-old oak possible. They provided a clean, historically sympathetic fix our client loved."
