Product Description
Simpson HDUE5-SDS3HDG HDUE 11-5/16 in. Hot-Dip Galvanized Predeflected Holdown with Strong-Drive SDS Screws by Simpson Strong-Tie is an engineered holdown connector built for securing shearwalls, braced wall panels, and other lateral-force-resisting applications in wood construction. Its predeflected seat design actively reduces deflection under load, delivering superior overturning resistance where structural reliability is critical.
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: 11-5/16 in.
- Made from 14-gauge steel
- Hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications

Frequently Asked Questions
- What fasteners are used to install the HDUE5-SDS3HDG?
- This holdown installs with a 5/8 in. anchor bolt and (10) 1/4 in. x 3 in. Strong-Drive SDS Heavy-Duty Connector screws, which are included with the product.
- Why does this holdown feature a predeflected seat?
- The predeflected seat is specifically engineered to reduce deflection under load, helping maintain the structural integrity and performance of shearwalls and lateral-force-resisting assemblies during dynamic loading conditions.
- Is the HDUE5-SDS3HDG suitable for use with treated lumber or exterior applications?
- Yes. The hot-dip galvanization (HDG) finish provides extra corrosion resistance, making this holdown well-suited for exterior installations and applications involving treated wood where standard coatings may be insufficient.
- What is the purpose of the overlapping back plate on this holdown?
- The overlapping back plate increases fastener strength and shear values while helping prevent post splitting, contributing to higher overall load capacity and a more reliable connection at the wood post.
