5 in x 1/4 in Simpson Strong-Tie Strong-Drive Double-Barrier Coated SDS Heavy-Duty Connector Screw

The Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screw is a 1/4"-diameter high-strength structural 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.
