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 stringent requirements of the 2006, 2009 and 2012 IBC for 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.

- Self-undercutting feature provides higher load carrying capacity than conventional mechanical anchors
- 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 expansion cone minimizes binding and speeds installation
- Installs just like a conventional expansion anchor, no special tool, drill bit, or secondary drilling is required
- The head is stamped with the Simpson Strong-Tie® "≠" sign and size identification for easy post installation verification

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
Interior environment where low levels of moisture and corrosive chemicals are present.
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.

Torq-Cut™ Anchor Material Specifications
- 3/8" TCA uses ASTM A193 Grade B7 rod. 1/2", 5/8" and 3/4" TCA uses ASTM A193 Grade B7M rod.
Drilled Hole Depth
- The notation in parentheses is for the 2006 IBC.
- The Drilled Hole Depth is 1/2" greater than the Nominal Embedment Depth.
- For the Through-Set version of the Torq-Cut anchor, if the actual Fixture Thickness (tfix) is less than the Maximum Fixture Thickness (F), the Minimum Drilled Hole Depth (A) must be increased as follows:
Drilled Hole Depth = A + (F-tfix)Similarly, the Minimum Effective Embedment Depth (C) is increased as follows:
Effective Embedment Depth = C + (F-tfix)
