Strong-Drive SWD Double-Threaded Screw

Simpson Strong-Tie has extended its line of structural fasteners with the launch of the Strong-Drive SWD Double-Threaded screw. It is a low-profile structural screw with a compact, cap-style head to reduce its visibility and suitable for applications including beam-to-post, beam-to-joist, purlin-to-truss, guardrail-to-post and roof-to-wall connections; multi-ply assemblies; knee bracing; cap connector replacements; and post-frame connections. The SWD Double-Threaded screw’s unique double-thread design with differentiated thread geometries and smooth mid-shank holds wood members together tightly. It features a black exterior double-barrier coating for corrosion resistance and a chisel tip for fast starts, easy driving at any angle and reduced splitting.

Code-approved, the SWD Double-Threaded screw is available in various lengths, from 2 1/2 inch to 10 3/4 inch".
