It stands 10-3/8 in. tall with a G90 galvanized finish and installs with #14 self-drilling tapping screws, which are sold separately. One holdown per order unit.
Key Features
- CFS Framing: Used as a cold-formed steel framing connector where structural steel members require stud-to-foundation or floor-to-floor connections.
- Screw Install: Installs with #14 self-drilling tapping screws, saving time and labor.
- Low Deflection: Pre-deflected geometry virtually eliminates material stretch, resulting in low deflection under load.
- 5/8 in. Anchor: Accepts a 5/8 in. diameter foundation anchor.
- Galvanized Finish: G90 zinc galvanized coating for corrosion resistance in dry environments.
- Versatile Mounting: Supports wood-to-steel, steel-to-steel, and steel-to-concrete installations.

Product Expert Notes
Choose the S/HDU6 when your cold-formed steel shearwall or chord needs a holdown that combines performance with screw installation. Its pre-deflected geometry keeps deflection low under load, which matters for wall performance. Confirm the required holdown model and anchor size with your project's engineered drawings, and use all specified screws and the correct 5/8 in. anchor to achieve rated capacities.
Holdowns are structural components; follow the engineer of record's fastener and anchor schedule, and use all specified fasteners to achieve published load values.
