The construction industry worldwide is looking closely at how new fastener technology can replace traditional connectors. This aims to make structures safer and stronger, while also increasing builder productivity.

These dual benefits are clearly evident in Simpson Strong-Tie's SDWC Truss Screw. Used in stud-to-top and bottom plate connections, as well as truss/rafter-to-top-plate connections, these fully threaded screws distribute the load evenly over the full length of the connection instead of relying solely on the head to provide clamp force. The SDWC Truss Screw offers an easier and faster alternative to conventional framing straps and angle brackets.

The SDWC Truss screw comes with rigorous testing engineering data to back it up. Its cap head design countersinks fully into the double top plate to avoid interference with plasterboard or finishing trades. For easier starts and driving, the SDWC Truss screw features a self-drilling Type-17 point. Its fully-threaded shank creates a secure connection you can trust!
