Steel Rod Hanger Threaded Rod Anchor System

Steel Rod Hanger

The Simpson Strong-Tie® steel rod hanger is a one-piece fastening system for suspending 1/4" and 3/8" threaded rod. Vertical rod hangers are designed to suspend threaded rod in overhead applications from steel joists and beams. Horizontal rod hangers are available for applications requiring installation into the side of joists, columns and overhead members. Both rod hangers provide attachment points for use in pipe hanging, fire protection, electrical conduit and cable-tray applications. Recommended for use in dry, interior, non-corrosive environments only.

Key Features

  • Threaded anchors for rod-hanging applications in steel members
  • Suitable to be installed horizontally or vertically in overhead applications
  • Self-drilling, no predrilling required, easily installed with a drill or screw gun
  • Custom-matched nut driver sets anchor to optimal depth
  • UL/FM listed

Warning

  • Recommended for use in dry, interior, non-corrosive environments only

  1. Allowable loads are based on a factor of safety calculated in accordance with AISI S100 Section F1.
  2. Mechanical and plumbing design codes may prescribe lower allowable loads. Verify with local codes.
  3. Model requires installation with supplied retaining nut.
  4. Values are based on steel members with the following minimum yield and tensile strengths:
    • 43 mil (18 ga.) and 33 mil (20 ga.): Fy = 33 ksi and Fu = 45 ksi
    • 54 mil (16 ga.) to 97 mil (12 ga.): Fy = 50 ksi and Fu = 65 ksi
    • 3/16" and 1/4": Fy = 36 ksi and Fu = 58 ksi
  5. Minimum edge distance must be 1" and minimum spacing must be 2".
  6. Acceptability of base material deflection due to imposed loads must be investigated separately.
