STRONG-BOLT® 2Wedge Anchor for Cracked and Uncracked Concrete


The Strong-Bolt® 2 wedge anchor is the next-generation solution for cracked and uncracked concrete. Following rigorous testing according to ICC-ES acceptance criteria, the Strong-Bolt 2 anchor received classification as a Category 1 anchor*, the highest attainable anchor category for performance in cracked concrete under static and seismic loading. Available in stainless steel, it is code-listed by ICC-ES under the 2012 IBC requirements for post-installed anchors in cracked and uncracked concrete.

Available in the popular 3/8″ diameter, the Strong-Bolt 2 anchor is ideal for MEP applications in cracked concrete, such as hanging pipes, struts, equipment anchorage and other fixtures overhead. The anchor is also effective for lightweight- concrete applications, including concrete-over-metal decking.

The Strong-Bolt 2 wedge anchor in type 316 stainless steel** also offers optimum performance in both cracked and uncracked concrete, meeting 2012 IBC standards for post-installed anchors. This wedge anchor is ideal for corrosive environments, including construction in coastal areas, wastewater and sewage treatment facilities, food processing facilities, pulp and paper mills, and other high-exposure environments.



  • Category 1 anchor classification: The Strong-Bolt 2 anchor received classification as a Category 1 anchor, which is established by performance in reliability tests in accordance with AC193 and ACI355.2 test criteria. Category 1 is the highest attainable anchor category for reliability.
  • Tri-segmented clip: Each segment adjusts independently, increasing follow-up expansion should the hole increase in size as a result of a crack.
  • Dual embossments on each clip segment: Enables clip to undercut into the concrete thereby increasing follow-up expansion should a crack occur.
  • The 3/8″ anchor solution approved for 3 ¼” concrete thickness: The Strong-Bolt 2 anchor can be installed in cracked concrete with a minimum thickness of 3 ¼“, including concrete-over-metal decking.
  • High-strength alloy clip on carbon-steel anchors: This special alloy clip offers improved performance.
  • Standard (ANSI) fractional anchor: Fits most fixtures and installs with common drill bit sizes and tools.
  • Type 316 stainless-steel clip on stainless steel anchors: In addition to superior corrosion resistance, a stainless-steel clip offers “memory” that contributes to the anchor’s performance if the hole increases in size because of a crack.
