Description

The Simpson Strong-Tie HDUE 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 HDUE series provides enhanced lateral load support for demanding shearwall applications. The included SDS structural screws create a strong, code-compliant connection to wood studs or posts while simplifying installation.

Featuring a pre-deflected body, this structural connector reduces deflection under tension for tighter, more consistent performance. Available in multiple sizes and finish options, the HDUE holdown can be selected based on required load capacity 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 and reliable installation.
Pre-Deflected Design: Minimizes deflection under load for improved structural performance.
Shearwall Anchorage: Secures wall ends and vertical framing members to foundations.
Finish Options: Available in corrosion-resistant finishes for interior or exterior use.

HDU/HDUE/HDQ/HHDQ Holdowns

Holdowns and Tension Ties Reinforce Structural Connections

Holdowns and Tension ties are designed to strengthen critical structural connections where uplift and lateral forces occur. Commonly used in shear walls, deck connections, and wood framing, holdown anchors and tension ties help transfer loads from framing members to the foundation, reducing movement and improving overall structural stability.
Precision Fit for Critical Framing Connections

Tension ties and holdown connectors feature prepunched holes that allow accurate fastener placement and proper alignment during installation. These connectors reinforce high-load framing areas where standard fasteners alone may not provide sufficient strength.
Corrosion-Resistant for Outdoor Durability

Holdown anchors and deck tension ties are often installed in exterior environments where moisture and treated lumber are present. Many Simpson Strong- Tie connectors feature corrosion-resistant finishes like ZMAX or stainless steel to help maintain long-term strength and performance.
