These high-performance timber screws are specifically designed to provide contractors and DIYers with a powerful, easy-to-install alternative to traditional lag screws and through-bolting methods. Measuring 5 inches in length and crafted from high-quality stainless steel, each screw is coated with a Double-Barrier finish that enhances durability and corrosion resistance, making them ideal for long-term outdoor use in a wide range of weather conditions. The bold threading ensures superior holding power, while the patented 4CUT tip eliminates the need for predrilling, reducing installation torque and allowing for fast and efficient starts. The low-profile washer head offers a wide bearing surface for greater stability and control, and under-head nibs help seat the head cleanly. These screws also feature size markings on the head for easy identification and a T-40 6-lobe star drive to minimize cam-outs, extending the life of your driver bits. The included driver bit and self-drilling capability make installation quick and hassle-free. Perfect for structural wood framing applications such as decks, ledgers, and other load-bearing projects, these screws meet IRC and IBC code requirements and are IAPMO UES ER-192 certified.
