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 tapping screws into the studs reduces installation time and saves labor cost.

Material: 118 mil (10 ga)

Finish: Galvanized

top Load Table: See code report listings below
Table
  1. Designer shall specify the foundation anchor material type, length, embedment and configuration. Tabulated loads may exceed anchor bolt ASTM A36 or A307 tension capacities.
  2. See anchor bolt options: SB Anchor Bolts, SSTB Anchor Bolts, RFB Retrofit Bolts, PAB Pre-Assembled Anchor Bolts.
  3. See anchor bolt retrofit options.
  4. Stud design by Specifier. Tabulated loads are based on a minimum studs thickness for fastener connection.
  5. 1/4" self-drilling tapping screws can be substituted for #14.
  6. Heavy hex nut is required to achieve the table loads for S/HDU11.
  7. Deflection at ASD and LRFD Loads includes fastener slip, holdown elongation and anchor bolt elongation (L=4").
  8. Nominal Tension Load is based on the average ultimate (peak) load from tests. AISI Lateral Design standard requires holdown to have nominal strength to resist lesser of amplified seismic load or the maximum force the system can deliver.
