The Strong-Drive® SDWC truss screw provides a stud-to-bottom plate or stud-to-top-plate connection as well as fastening trusses and rafters to top-plates. The full-threaded shank engages the entire length of the fastener, providing a secure connection. The SDWC is tested in accordance with ICC-ES AC233 (screw) and AC13 (wall assembly and roof-to-wall assembly) for uplift and lateral loads between wall plates and vertical wall framing and between the top-plate and the roof rafters or trusses.

• Cap-style head countersinks fully into the double-top-plate to avoid interference with drywall or finish trades
• Wide tolerance on installation angle makes it easy to install the SDWC correctly
• Can be installed from inside the structure, eliminating exterior work on the upper stories and enhancing job safety
• Fastening can be performed before or after exterior sheathing is applied for added flexibility
• Type-17 point for faster starts and easier driving
• Orange color for easy inspection
• Matched-tolerance driver bit (included) engages fastener head securely to allow one-handed driving
