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.

\r\n\r\n

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.

Cap Head countersinks fully into the double top plate to avoid interference with plasterboard or finish trades
Orange colour for easy inspection of 152 mm screws
Fully-threaded shank engages the entire length of the fastener, providing a secure connection between the roof and wall framing members
Type-17 Point for faster starts and easier driving
Wide tolerance on installation angle makes it easy to install the SDWC correctly — Installation guide included to help ensure proper installation angle
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
Installation guide included in pack to help ensure proper installation angle
