Trubolt® Wedge Anchors


Red Head Wedge Anchor Voluntary Product Withdrawal

ICC Evaluation Services (“ICC-ES”) recently reissued ESR-3772 to remove recognition of cracked concrete and seismic design for Red Head Trubolt+ wedge anchors. As a result, Red Head is voluntarily withdrawing certain Red Head Trubolt and Trubolt+ wedge anchors from the marketplace while internal and independent testing is conducted and we continue to work with ICC-ES. Please visit for additional information.


Trubolt Wedge anchors feature a stainless steel expansion clip, threaded stud body, nut and washer. Anchor bodies are made of plated carbon steel, hot-dipped galvanized carbon steel, type 304 stainless steel as identified in the drawings or other notations.

The exposed end of the anchor is stamped to identify anchor length. Stampings should be preserved during installation for any subsequent embedment verification.

Use carbide tipped hammer drill bits made in accordance with ANSI B212.15-1994 to install anchors.

Anchors are tested to ACI 355.2 and ICC-ES AC193. Anchors are listed by the following agencies as required by the local building code: ICC-ES, UL, FM, City of Los Angeles, California State Fire Marshal and Caltrans.

  • Versatile fully threaded design is standard on sizes up to 3/4" diameter and 10" length
  • Anchor diameter equals hole diameter
  • One piece stainless steel expander clip resists corrosion
  • Standard carbon and stainless steel anchors
  • 360° contact with concrete assures full expansion for reliable working loads
  • Non bottom-bearing, may be used in hole depth exceeding anchor length
  • Can be installed through the work fixture, eliminating hole spotting
  • Inspectable torque values, indicating proper installation


Anchoring machinery and conveyors is a common wedge anchor application. The Trubolt is fully threaded to allow a large range of embedment and fixture thickness.

Seismic Wedge Anchor cracked concrete approval controls tension & shear simultaneously.
