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.

• Higher shear values than competitive products enable wider spacing, saving time and money
• Bold thread design provides superior holding power and cinches fastened members together for consistent installation
• SawTooth® point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
