Simpson Strong-Tie is extending its line of structural fasteners with the launch of the Strong-Drive SWD Double-Threaded screw. With its innovative design, the SWD wood-to-wood screw can replace some interior and exterior connectors, potentially reducing installation times and labor costs, the company said.
Designed for stealth, strength and speed, the SWD Double-Threaded screw is a low-profile structural screw with a compact, cap-style head to reduce its visibility. The 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.
