The Simpson Strong-Tie Strong-Drive SDS heavy-duty connector screw is a 0.25 in Dia high-strength structural wood screw ideal for various connector installations as well as wood-to-wood and engineered-wood applications. It installs with no pre-drilling and has been extensively tested in various applications. The SDS is improved with an easy-driving Type-17 point and a corrosion-resistant double-barrier coating. The SDS Strong-Drive 1/4 in wood screw line has expanded to include stainless steel SDS screws in 1-1/2 to 3-1/2 in lengths, suitable for fastening Simpson Strong-Tie stainless steel products. Offering the same easy-driving, split-reducing installation of the standard SDS screw, these screws are made from Type 316 stainless steel. The stainless steel SDS screws are appropriate for higher-exposure environments where maximum corrosion resistance is required.
