Strong-Drive® SDW™ Truss-Ply Screw

The Strong-Drive SDW Truss-Ply screw is a high-strength structural wood screw specifically designed for fastening multi-ply wood members, such as joining plated trusses and solid-sawn lumber. The SDW installs easily with no predrilling and is available in optimized lengths for fastening 2-, 3- and 4-ply trusses. With the SDW Truss-Ply screw, multi-ply trusses and components can be fastened from one side without requiring the lifting and flipping of heavy assemblies. It is code listed in IAPMO UES ER-192 and meets 2018 and 2021 IRC® and IBC® code requirements for most common wood framing applications with wood and engineered wood.

Key Features
  • Large washer head with nibs provides maximum bearing area; stamped with the Simpson Strong-Tie “≠” sign and fastener length for easy identification after installation
  • 6-lobe, T40 drive provides positive engagement that makes the screw easy to drive and improves bit life (replacement bit — BIT40T-134-R2)
  • Low-profile head results in less interference after installation; makes stacking and sliding members easier and allows installation of hardware and finishes to be virtually flush
  • Higher shear values than competitive products enable wider spacing, saving time and money
