The Simpson Stainless Steel 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 a patented easy driving Type-17 point and a corrosion-resistant double-barrier coating. Stainless-steel SDS screws are appropriate for higher-exposure environments where maximum corrosion-resistance is required.
