Simpson Strong-Tie HDUE Holdown, Hot-Dip Galvanized

The patent-pending HDUE holdown is designed to meet the increased design demands of today’s residential wood structures, including three-story homes with more windows and limited shearwall space. Offering higher load capacities than previous models, the HDUE serves as an easy one-to-one replacement for our industry-leading HDU. This holdown provides exceptional overturning resistance for shearwalls, braced wall panels and other lateral-force-resisting applications in wood construction.

Tested per ICC-ES AC155, the higher-capacity models combine fasteners in both shear and tension while reducing the number of screws required. The HDUE is fast and easy to install with Strong-Drive® SDS Heavy-Duty Connector screws (included), minimizing fastener slip and preserving the wood post’s net section better than bolts. Available in multiple sizes, the HDUE accommodates a wide range of load requirements.

• Predeflected seat reduces deflection under load
• Angled fastening in the four larger sizes engages the screws in tension for higher load capacity, reducing the number of screws required
• Angled fastening tabs in the four larger sizes help drive the fastener at a 45° angle, and offset holes on the second back plate block the fastener from being driven straight
• Overlapping back plate increases fastener strength and shear values, helping prevent post splitting
• Optimized screw patterns reduce splitting at the end of the post and maximize individual fastener capacity
• Installs with Strong‑Drive SDS Heavy‑Duty Connector screws (included)
• Extruded seat adds a greater cross-sectional steel section for added strength
• Teardrop holes allow higher and more even distribution of load
