Strong-Drive® SDS Heavy-Duty Connector Screw
The Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screw is a 0.250"-diameter high-strength structural wood screw ideal for various connector installations as well as wood-to-wood and engineered wood applications. It installs with no predrilling 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" wood screw line has expanded to include stainless-steel SDS screws in 1 1/2" to 3 1/2" 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.
Strong-Drive® SD Connector Screw
The Strong-Drive SD Connector screw is specifically designed to replace nails in certain Simpson Strong-Tie connectors and is the only screw approved for that application. The load-rated SD screw has been tested and approved for use in many popular Simpson Strong-Tie products. In certain applications screws are easier and more convenient to install than nails, and the single-fastener load values achieved by the SD screw exceed those of typical 10d common or 16d common nails. In addition, the galvanized coating makes the SD screw ideal for interior and most exterior conditions.
