Simpson Strong-Tie Strong Drive Screws

Simpson Strong-Tie has released a new single-screw solution for truss and rafter uplift and lateral loads, the Strong-Drive® Structural Wood Screw.

The Strong-Drive® SDWC provides a time-saving and reliable option to fastening trusses and rafters to wall top plates. The SDWC offers fully tested loads in accordance with ICC-ES AC233 (screw) and ICC-ES AC13 (roof-to-wall assembly), and installs easily and effectively without pre-drilling.


  • Fully-threaded shank engages the entire length of the fastener, providing a secure connection between the roof and wall framing members
  • Cap-style head countersinks fully into the double top plate to avoid interference with drywall or finish trades
  • Wide installation-angle range makes it easier 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
  • Metal installation guide tool (included) to help ensure proper installation
  • Matched-tolerance driver bit (included) engages fastener head securely to allow one-handed driving (replacement bit part no. BIT30T-R1)
  • Type-17 point for faster starts and easier driving
