The TCA self-undercutting anchor is a heavy-duty, high-capacity anchor developed and tested for use in cracked and uncracked concrete under static and seismic conditions. The TCA features a built-in, hardened cutting ring that expands with installation torque, forming undercut grooves in the concrete. This interlock between the anchor and the concrete provides superior load-carrying capacity.
