SWW Structural Washer Head Wood Screw

SWW is a washer head structural screw designed for load-bearing wood structures. The SWW screw has a milling thread to allow for smooth driving of the shank. The large washer head gives high head pull-through resistance while allowing the wood members to close up firmly.

advantage

The pan head enlarges the contact surface and ensures a higher
ensures a higher head pull-through resistance as well as a greater
load transmission.

The cutting tip design in conjunction with the reaming shank
efficient and smooth screwing with simultaneous minimization of the
minimizing the insertion resistance and reducing the splitting effect.
