The Strong-Drive SDW screw is a 0.22 inch diameter, high-strength structural wood screw specifically designed for fastening multi-ply wood members such as plated trusses, engineered-lumber products and solid-sawn lumber. The SDW installs easily with no pre-drilling and is available in optimized lengths for fastening 2, 3 and 4-ply trusses or 1 3/4 inch engineered lumber. The SDW enables single-side fastening, while still allowing concurrent loading on both sides of the assembly to the full allowable head or tip-side load of the fastener.
