Simpson Strong-Tie SDW Truss-Ply Screws are designed for high-strength fastening in double-ply trusses, studs, and other multi-ply wood assemblies. Whether you’re reinforcing floor systems, framing a load-bearing wall, or tying together structural members, these screws provide the grip and holding power needed for code-compliant interior connections.

Each screw features a sharp, self-starting tip that eliminates pre-drilling and drives fast into engineered or dimensional lumber. The oversized washer-style head delivers consistent clamping pressure to ensure strong, tight joints every time.
