The Strong‑Drive® SDWC Truss Screw provides a truss and rafter-to-top plate connection as well as a method to fasten stud-to-top and bottom plate. The fully-threaded shank engages the entire length of the fastener providing a secure connection.

The SDWC uplift values listed were analysed and calculated based on the characteristic values determined following AS1649-2001 (Timber-Methods of Test for Mechanical Fasteners and Connectors-Basic Working Loads and Characteristic Strength). The SDWC has also been 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.
