Simpson Strong-TieSimpson Strong-Tie screw

The new Simpson Strong-Tie Strong-Drive® SDWH Timber Hex-HDG screw requires no pre-drilling and replaces bolt, washer and nut assemblies, saving installers time and cost. This .276-inch diameter hot-dip galvanized screw features a SawTooth point and oversized integral washer, which eliminate the need for pre-drilling and a separate washer. Reducing the installation time with a fast, easy driving screw is particularly beneficial to installers who are either on a lift or suspended 15 feet off the ground drilling holes through 12- to 14-inch thick piles. The screw’s hot-dip galvanized coating meets the requirements of ASTM A153, Class C, making it suitable for heavy-duty applications. Another key benefit is the ability to install it from one side of the pile. The SDWH Timber Hex-HDG screw is available in five lengths, ranging from 4 inches to 12 inches, and features a 3/8-inch hex-drive head for secure driving. For more information, click here.
