TCA Self-Undercutting Anchor

Product Details

TCA is available on a special-order basis only; minimum order quantities will apply. Contact your local Simpson Strong-Tie representative for more information.

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.

Key Features

Code listed under IBC/IRC for cracked and uncracked concrete per ICC-ES ESR-2705
Self-undercutting feature provides higher load-carrying capacity than conventional mechanical anchors
Qualified for static and seismic loading conditions (seismic design categories A through F)
Ductile steel rod provides consistent, reliable performance
Specially designed, low-friction expansion cone minimizes binding and speeds installation
Installation requires no special drill bit or secondary drilling operation
Head is stamped with the Simpson Strong-Tie^® “≠” sign and anchor size identification for easy post-installation verification

Material

Carbon steel

Finish

Zinc-plated or sherardized

Installation

Installation Instructions: Pre-Set Version

Drill a hole in the base material to the specified embedment depth using the appropriate diameter carbide drill bit specified for each diameter.
Blow the hole clean using compressed air.
Assemble the anchor with nut and washer and finger-tighten nut so all components are snug (spacer sleeve, expansion sleeve and cone). The bottom of the threaded rod should be flush with the bottom of the cone.
Place the anchor into the drilled hole and use a hammer and setting tool to drive the anchor until the washer and nut are tight against the surface of the base material.
Remove the nut and washer and install the fixture. Re-assemble the nut and washer over the fixture.
Tighten to the required installation torque.

Installation Instructions: Through-Set Version

Drill a hole in the base material to the specified embedment depth using the appropriate diameter carbide drill bit specified for each diameter.
Blow the hole clean using compressed air.
Assemble the anchor with nut and washer and finger tighten nut so all components are snug(spacer sleeve, expansion sleeve and cone). The bottom of the threaded rod should be flush with the bottom of the cone.
Place the anchor through the fixture and into the drilled hole. Use a hammer and setting tool to drive the anchor until the washer and nut are tight against the fixture.
Tighten to the required installation torque.

Caution

Oversized holes in the base material will make it difficult to set the anchor and will reduce the anchor’s load capacity. Do not use an impact wrench to set or tighten the anchor.
