Simpson Strong Tie HDU2-SDS2.5 Hold Down Connector

Product Description

The SIMPSON STRONG TIE HDU2-SDS2.5 is a predeflected hold down connector designed to resist uplift and lateral loads in light-frame wood construction. The predeflected design accounts for wood shrinkage and fastener slip, maintaining consistent tension between the anchor bolt and the framing member over time. Installers drive SDS2.5 structural screws directly into the post or stud, eliminating the need for through-bolts on the wood-side connection. This connector is field-installed by framing contractors, structural carpenters, and general contractors working to engineer-specified shear wall assemblies.

The HDU2-SDS2.5 is suited for residential and light commercial wood-frame projects where engineered shear walls are required. Typical applications include multi-story platform-frame construction, shear wall hold down at corners and wall ends, and anywhere an engineer of record specifies a code-listed tension tie. The predeflected feature makes it a common choice on projects where post-installation wood shrinkage must be accounted for in the structural design.

Key Features

• Predeflected design compensates for wood shrinkage and connector slip after installation
• Compatible with SDS2.5 structural screws on the wood-side connection for faster installation
• Suited for engineered shear wall assemblies in residential and light commercial construction
• Sold in a package quantity of 20 units, supporting multi-wall or multi-story job-site requirements
• Code-listed connector backed by Simpson Strong-Tie engineering documentation

Compatibility

Designed as an OEM-style structural connector for light-frame wood construction shear wall assemblies where a predeflected hold down is specified by the engineer of record.

Installation Notes

Installation should be performed by a qualified framing contractor or structural carpenter in accordance with the project engineer's drawings and applicable building code requirements. Verify anchor bolt diameter, embedment depth, and post or stud size against the load table before fastening. Use only the specified SDS2.5 structural screws in the quantity and pattern indicated in the manufacturer's installation instructions. Do not substitute fastener type or quantity, as doing so may void the code listing and alter the rated load capacity.
