The Simpson Strong-Tie HDU Holdown is a high-capacity structural holdown designed to anchor wood shearwalls and posts to concrete foundations. It transfers uplift and overturning forces from wood framing into the foundation, helping protect structures in high-wind and seismic conditions.
Built for high uplift resistance, the HDU series provides strong lateral load support for demanding shearwall end connections. The included SDS structural screws create a secure, code-compliant attachment to wood studs or posts while streamlining installation.
Featuring a pre-deflected body, this structural connector reduces deflection under tension for tighter performance under load. Available in multiple sizes and corrosion-resistant finishes, the HDU holdown can be selected based on structural demand and environmental exposure.
Key Features:
- High Load Capacity: Designed to resist significant uplift and overturning forces.
- SDS Screws Included: Pre-engineered structural screws provide fast, reliable installation.
- Pre-Deflected Design: Minimizes deflection under tension for improved performance.
- Shearwall Anchorage: Secures wall ends and vertical framing members to foundations.
- Finish Options: Available in corrosion-resistant finishes for interior or exterior applications.
