Product Description
Simpson HDUE3-SDS3 HDUE 8-11/16 in. Galvanized Predeflected Holdown with Strong-Drive SDS Screws is a heavy-duty holdown connector from Simpson Strong-Tie engineered to deliver exceptional overturning resistance for shearwalls, braced wall panels, and other lateral-force-resisting applications in wood construction. Its predeflected seat design minimizes deflection under load, while an overlapping back plate and optimized fastener patterns work together to maximize strength and help protect the integrity of the wood post.
Key Features
- Predeflected seat reduces deflection under load
- 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
- Extruded seat adds a greater cross-sectional steel section for added strength
- Teardrop holes allow higher and more even distribution of load
- Height: 8-11/16 in.
- Made from 14-gauge steel
- Galvanized (G90) for corrosion resistance

Frequently Asked Questions
- What fasteners are used to install the HDUE3-SDS3?
- The HDUE3-SDS3 installs with a 5/8 in. anchor bolt and (7) 1/4 in. x 3 in. Strong-Drive SDS Heavy-Duty Connector screws, which are included with the holdown. Using SDS screws minimizes fastener slip and helps preserve the wood post's net section.
- What is the purpose of the predeflected seat on this holdown?
- The predeflected seat is specifically engineered to reduce deflection under load, helping the holdown maintain tighter tolerances and better performance in lateral-force-resisting applications compared to standard non-predeflected designs.
- What material and coating is used on the HDUE3-SDS3?
- The HDUE3-SDS3 is made from 14-gauge steel and features a Zinc Galvanized (G90) coating, which provides corrosion resistance for added durability in typical residential construction environments.
- How do the teardrop holes benefit the HDUE3-SDS3's performance?
- The teardrop holes are designed to allow higher and more even distribution of load across the holdown, contributing to the connector's overall strength and structural efficiency.
