SWD

Structural Double Threaded Wood Screw

SWD is a construction screw designed to connect two timber members together. The small cap-style head and double thread creates a flexible, hidden assembly with high strength. The differentiated thread pitch creates a clamping effect, reducing the risk of gaps between the timber members.
