Cold-Formed Steel: S/HDU Holdowns

The S/HDU series of holdowns combines performance with ease of installation. The pre-deflected geometry virtually eliminates material stretch, resulting in low deflection under load. Installation using self-drilling screws into the studs reduces installation time and saves labor cost.

Available 1st Quarter 2008

Material: 118 mil (10 ga)

Finish: Galvanized

Installation:

Use all specified fasteners. See General Notes.
Use #14 screws to fasten to studs
For the S/HDU11 use heavy hex nuts on the anchor bolt.

S/HDU		Typical S/HDU Installation

Heavy hex nut is required to achieve the table loads for S/HDU11.
Allowable tension loads for S/HDU11 with regular hex nut for 2-43 mil is 9595 lb. and for 2-54 mil is 9675 lb.
The Designer shall specify the anchor embedment and configuration. See SSTB Anchor Bolts.
Back-to-back stud members are required unless otherwise specified.
1/4” self-drilling screws can be substituted for #14.
See Holdown and Post Base Anchor Solutions for anchor bolt retrofit.
Tabulated loads shown at (100) do not include steel stress increase. Tabulated loads shown at (133) include a 1/3 stress increase on the steel. Refer to Steel Stress Increase for additional information.
Deflection Load: The deflection of a holdown measured between the anchor bolt and the strap portion of the holdown when loaded to the highest load listed in the catalog table. This movement is strictly due to the holdown deformation under a static load test with attached to members listed in the table above.
Nominal Tension Load is based on the average peak load from tests. AISI Lateral Design standard requires holdown to have nominal strength to resist lesser of amplified seismic load or what the system can deliver.
