Description
The Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screw is a 1/4 inch diameter high-strength structural wood screw ideal for various connector installations as well as wood-to-wood applications. It installs with no predrilling and has been extensively tested in various applications. The SDS is improved with a patented easy driving 4CUT tip and a corrosion-resistant double-barrier coating. The SDS Strong-Drive 1/4 inch wood screw line has expanded to include stainless-steel SDS screws in 1 1/2 inch to 3 1/2 inch 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 new stainless-steel SDS screws are appropriate for higher-exposure environments where maximum corrosion-resistance is required.
