LSTHD/STHD Strap-Tie Holdowns

LSTHD & STHD Strap-Tie Holdowns

LSTHD and STHD Strap-Tie Holdowns are engineered structural connectors designed to resist uplift and tension forces in wood framing systems. Unlike traditional rigid holdowns, these strap-style connectors provide high-capacity tension resistance with greater installation flexibility.

At Fasteners Plus, we carry Simpson Strong-Tie LSTHD and STHD strap-tie holdowns built for dependable, code-compliant performance in residential and light commercial construction. Whether reinforcing shear walls or strengthening wood-to-wood connections, these holdowns help maintain continuous load paths in demanding applications.

What Are Strap-Tie Holdowns Used For?

Strap-tie holdowns are typically installed to resist uplift and overturning forces in shear wall assemblies and structural framing systems. Their extended strap design allows for distributed fastening across multiple framing members.

• Shear Wall Reinforcement: Anchor wall framing to resist tension forces.
• Wood-to-Wood Connections: Strengthen multi-member assemblies.
• High-Wind & Seismic Applications: Improve structural stability under dynamic loads.
• Continuous Load Path Reinforcement: Maintain proper tension transfer through framing systems.

LSTHD vs. STHD — What’s the Difference?

• LSTHD Strap-Tie Holdowns: Designed for high-capacity tension resistance with extended strap length for distributed fastening.
• STHD Strap-Tie Holdowns: Compact strap-style holdowns for structural reinforcement in various framing applications.

Model selection depends on allowable load requirements, framing configuration, and installation specifications.
