The Simpson S/HD8S S/HDS 11 in. Light Gauge Steel Holdown by Simpson is a cold-formed steel holdown engineered to deliver reliable load performance for high-load shearwalls, braced-wall panels, and lateral applications. Its unique seat design greatly minimizes deflection under load, while its screw-based fastening system is optimized to use fewer fasteners and reduce installation time - making it a practical choice for both direct-on-track and raised installations in light gauge steel framing.

Key Features

• Unique seat design that greatly minimizes deflection under load - helps maintain structural integrity in high-load shearwall and lateral applications, reducing movement where it matters most.
• Installs with #14 screws using fewer fasteners - cuts down on hardware count and speeds up installation time on the job site.
• Can be installed directly on the base track or raised above it - gives installers flexibility to meet varying site conditions without sourcing a different connector.
• Suitable for back-to-back applications where eccentricity is a concern - designed to handle paired installations cleanly, reducing the risk of load imbalance in braced-wall panel assemblies.
• Made from 118 mil (10 ga.) steel with a Simpson Strong-Tie gray paint finish - heavy-gauge construction provides the material strength required for high-load lateral connections.
• Screw-driven installation (S/HDS model) - for projects requiring bolt attachment to a post or column, the S/HDB model is the appropriate alternative, keeping each connector purpose-matched to its application.

Why This Product

• Engineered specifically for high-load lateral demands - the S/HD8S is purpose-built for high-load shearwalls, braced-wall panels, and lateral applications, so structural professionals get a connector sized and rated for demanding load conditions rather than a general-purpose alternative.
• Deflection-minimizing seat design adds reliability under stress - the unique seat that greatly minimizes deflection under load is a design advantage for applications where maintaining tight tolerances and minimizing movement is critical to wall panel performance.
• Installer-friendly design reduces labor on site - fewer required fasteners and straightforward #14 screw installation mean less time spent per holdown, which adds up across a full shearwall layout.
• Flexible placement options suit a wide range of framing conditions - the ability to mount directly on the base track or raised above it, combined with suitability for back-to-back use, makes the S/HD8S adaptable to both standard and eccentricity-sensitive cold-formed steel framing configurations.

Frequently Asked Questions

What type of fasteners are used to install the S/HD8S?

The S/HDS model is designed for installation with #14 screws. It has been designed to utilize fewer fasteners to reduce installation time. For attachment to a post or column with bolts, refer to the S/HDB model instead.

Can the S/HD8S be used in back-to-back applications?

Yes. The S/HD8S can be installed directly on the base track or raised above it and is suitable for back-to-back applications where eccentricity is a concern.

How does the S/HD8S minimize deflection under load?

The S/HDS features a unique seat design that greatly minimizes deflection under load, making it well-suited for high-load shearwalls, braced-wall panels, and lateral applications.

What material and finish is the S/HD8S made from?

The S/HD8S is made from 118 mil (10 ga.) steel and features a Simpson Strong-Tie gray paint finish.
