Simpson Strong-Tie SDWH Structural Wood Screws - Exterior 12 Count

About This Product

If you're working on any kind of structural wood project, these Simpson Strong-Tie screws are absolute game-changers. They're designed as a high-strength alternative to traditional lag screws and through-bolting, but way easier to install. The bold thread design provides superior holding power that really grips the wood securely. One of the best features is the patented 4CUT tip - this thing ensures fast starts and reduced installation torque, which means you can usually skip pre-drilling in most applications. That saves so much time and effort on projects! The large washer head provides maximum bearing area, distributing the load nicely across the wood surface. They come with a double-barrier coating that makes them suitable for exterior use and preservative-treated wood, so you don't have to worry about corrosion issues outdoors. The screw diameter is 0.195 inches with a large hex head drive that gives you good torque transfer. A bit is included in the package, which is convenient - no searching for the right driver. These are specifically designed with shorter thread lengths for fastening multi-ply members like trusses, engineered lumber products, and solid-sawn lumber. The optimal screw lengths provide maximum penetration while preventing the point from protruding out the back of your material. Simpson is known for their quality construction products, and these screws definitely live up to that reputation. They're made in the United States, which is nice to know you're getting domestically manufactured quality. Whether you're building decks, framing, doing structural repairs, or any wood construction project, these screws make the job easier and more secure. The deep 6-lobe recess reduces cam-out, so you're not constantly fighting with your driver slipping. They're substantial enough for serious structural work but still easy to drive with the right tool. The double-barrier coating really holds up well - you can see the quality in the finish. Many contractors swear by these for critical connections where strength and reliability matter. They're one of those products that might cost a bit more than standard screws but are absolutely worth it for the time saved and peace of mind gained. If you want professional-grade results on your woodworking or construction projects, these Simpson structural screws deliver in spades.
