Strong-Tie SDWC Truss Screws

Simpson Strong-Tie SDWC Truss Screws for Code-Compliant Structural Connections

Simpson Strong-Tie SDWC Truss Screws are engineered for high-strength wood-to-wood structural connections in truss and framing applications. Designed as a code-compliant alternative to traditional lag screws and through-bolts, SDWC screws provide exceptional holding power with faster installation and no pre-drilling required in most applications.

Built for Truss and Framing Performance

SDWC screws feature a large-diameter shank and aggressive thread design that deliver superior shear and withdrawal values. The fully threaded design draws members tightly together, creating solid structural connections in roof trusses, rafters, and multi-ply framing assemblies.

The hex washer head allows for strong clamping force and easy installation with standard impact drivers, helping crews move faster without sacrificing strength or code compliance.

Common Applications

• Truss-to-top plate connections
• Rafter and ridge beam fastening
• Multi-ply beam and header assemblies
• Stud-to-plate and structural framing connections

Key Considerations

• Code Compliance: Designed to meet ICC-ES requirements for structural wood connections when installed per manufacturer specifications.
• Installation Speed: Eliminates the need for pre-drilling in most standard framing lumber.
• Head Style: Hex washer head provides strong clamping force and reduces cam-out.
• Corrosion Resistance: Protective coating suitable for interior and many exterior framing applications.
