The Torq-Cut™ self-undercutting anchor is a heavy-duty, high-capacity anchor designed and tested for use in cracked and uncracked concrete under static and seismic loading conditions. It is designed to meet the requirements that the 2006 IBC places on post-installed anchors. The built in ring with hardened cutters expands with installation torque forming undercut grooves in the concrete. This interlocking connection between the anchor and the concrete provides superior load carrying capacity.

- AC193 code tested to ensure outstanding performance in both cracked and uncracked concrete
- Excellent for resisting seismic and vibratory loads
- Suitable for seismic applications categories A-F
- Ductile steel rod provides consistent, reliable performance
- Specially designed, low-friction wedge cone minimizes binding and speeds installation

TEST CRITERIA
The Torq-Cut anchor has been tested in accordance with ICC-ES's Acceptance Criteria for Mechanical Anchors in Concrete Elements (AC193) and ACI 355.2 for the following:
- Static tension and shear loading in cracked and uncracked concrete
- Seismic and wind loading in cracked and uncracked concrete
- Performance in cracked concrete
APPLICATION
Interior environment where low levels of moisture and corrosive chemicals are present
SUGGESTED SPECIFICATIONS
Self-undercutting anchors shall have an expansion ring with undercutting teeth which expands by tightening the nut that pushes the ring into a cone expander via a spacer sleeve. The anchor shall have been tested and qualified for performance in cracked and uncracked concrete per ACI 355.2 and ICC-ES AC193. Undercut anchor shall be the Torq-Cut™ self-undercutting anchor from Simpson Strong-Tie, Pleasanton, CA, and be installed following the Simpson Strong-Tie instructions.
