Product Description
The Simpson S/HDB 11 in. Light Steel Bolted Holdown from Simpson Strong-Tie is engineered to deliver reliable load performance for high-load shearwalls, braced-wall panels, and lateral applications in cold-formed steel framing. Ideal for bolt-on installations where cold-formed steel stud manufacturers can prepunch the bolt holes, this holdown features a unique seat design that greatly minimizes deflection under load. Designed for installation with bolts into the studs or column, the S/HDB is a dependable choice for demanding light-gauge steel structural connections.
Key Features
- Flexible installation positioning - can be installed directly on the bottom track or raised above it, giving installers more layout options to suit varying field conditions
- Suitable for back-to-back stud applications where eccentricity is a concern - accommodates paired stud assemblies without introducing problematic load offset, supporting structurally sound connections in complex framing configurations
- Unique seat design that greatly minimizes deflection under load - helps maintain tighter structural tolerances and improved performance in high-load shearwall and lateral bracing systems
- Bolted attachment to studs or column - compatible with prepunched cold-formed steel studs, streamlining installation and ensuring a secure, consistent connection; refer to the S/HDS series for screw-attached alternatives
- Made from 118 mil (10 ga.) steel with a Simpson Strong-Tie gray paint finish - heavy-gauge construction provides the rigidity and durability required for high-load structural holdown applications
Why This Product
- Engineered for high-demand structural applications - designed to provide loads for high-load shearwalls, braced-wall panels, and lateral applications, making it a purpose-built solution for cold-formed steel framing projects where connection integrity is critical
- Deflection control built into the design - the unique seat design greatly minimizes deflection under load, which translates directly to a stiffer, more reliable holdown connection compared to conventional bracket-style alternatives
- Fits seamlessly into prefabricated CFS construction workflows - ideal for bolt-on applications where cold-formed steel stud manufacturers can prepunch the bolt holes, reducing on-site labor and supporting off-site fabrication processes
- Versatile placement for real-world framing conditions - installs directly on the bottom track or raised above it and works in back-to-back configurations where eccentricity is a concern, giving design and installation teams the flexibility to address a wide range of structural conditions
