Product Description
The Simpson S/HDS 17 in. Light Gauge Steel Holdown from Simpson is engineered to deliver reliable load performance for high-load shearwall systems, braced-wall panels, and lateral applications in cold-formed steel framing assemblies. Its unique seat design greatly minimizes deflection under load, and its screw-based fastening system is designed to utilize fewer fasteners, helping reduce installation time on the job site.
Key Features
- Designed for cold-formed steel framing with screw installation - purpose-built for light gauge steel construction, ensuring a secure, compatible connection without the need for bolted hardware.
- Unique seat design that greatly minimizes deflection under load - helps maintain structural integrity in demanding high-load shearwall and lateral load conditions, giving builders confidence in long-term performance.
- Installs directly on the base track or raised above it - flexible positioning options allow the holdown to adapt to different framing conditions without requiring additional components.
- Suitable for back-to-back applications where eccentricity is a concern - allows symmetrical pairing of holdowns to counteract off-center loading, broadening its use in complex framing layouts.
- Installs with #14 screws and uses fewer fasteners - reduces the total number of fasteners required compared to conventional holdown solutions, cutting labor time and material cost on each installation.
- Made from 171 mil (7 ga.) steel with Simpson Strong-Tie Gray Paint finish - heavy-gauge construction provides strength and durability, while the painted finish offers surface protection in finished framing assemblies.
Why This Product
- Built to handle high-load lateral demands - the S/HDS is specifically designed to provide reliable load capacity for high-load shearwall systems, braced-wall panels, and lateral applications, making it a practical choice for structurally demanding cold-formed steel projects.
- Deflection control engineered into the design - the unique seat that greatly minimizes deflection under load is not a generic feature but a deliberate engineering decision, reducing movement in the connection and supporting tighter tolerances in shearwall assemblies.
- Faster, simpler installation with fewer fasteners - because the S/HDS has been designed to utilize fewer fasteners, installers spend less time driving screws and more time moving through the project, which directly reduces labor on each holdown placement.
- Versatile placement options for real-world framing conditions - with the ability to install directly on the base track or raised above it, and suitability for back-to-back configurations where eccentricity is a concern, this holdown accommodates a wider range of layout scenarios without requiring design workarounds.
