This product's information may differ depending on the category of use. You are currently viewing details related to Strong-Drive® Interior Wood Screws. You can also view product information related to the category: Fasteners for the Quik Stik System

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 fully-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. It is code listed under IAPMO-UES ER-262 and meets 2018 and 2021 IRC® and IBC® code requirements for most common wood framing applications.

Key Features

  • 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 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
  • 6-lobe, T30 driver bit provides positive engagement that makes the screw easy to drive and improves bit life (replacement driver bit — BIT30T-2-R2)
  • Fastening can be performed before or after exterior sheathing is applied for added flexibility
  • Metal installation guide tool (included) to help ensure proper installation
  • Orange color for easy inspection
  • Type-17 point for faster starts and easier driving
  • SDWC15450 is recognized for use in chemically treated wood as described in the evaluation report


  • Truss/rafter-to-plate and stud-to-plate connections
