Simpson Strong-Tie
$15-$60 eachHold-Downs for Shear Wall and Structural Uplift Resistance
Hold-downs are heavy-duty connectors anchoring shear wall ends, posts, and studs to the foundation below, resisting overturning forces from wind and seismic events. They complete the continuous load path that building codes require.
Key Features
- Resists overturning uplift forces
- Completes continuous load path
- Required in shear wall construction
- Multiple capacity models
- Embeddable and surface-mount styles

Pros & Cons
Pros
- ✓ Critical structural safety connector
- ✓ Very high uplift resistance
- ✓ Code-required in many areas
- ✓ Published engineering values
Cons
- ✗ Expensive for high-capacity models
- ✗ Complex multi-fastener installation
- ✗ Must be engineer-specified
Installation Tips
Install per engineer's specifications - model, anchor bolt size, and fasteners are all critical. Anchor bolt must have proper embedment. Don't overtighten bolts in wood.
