The Strong-Bolt® 2 wedge anchor is a wedge-style expansion anchor for use in solid concrete and lightweight concrete over metal deck. It sets like standard wedge anchors and is designed to offer optimum performance in both cracked and uncracked concrete applications. The anchor is available in the popular 3⁄8" size that is code-approved for 3 ¼" concrete thickness.


  • Can be installed in cracked concrete with a minimum thickness of 3-1/4 in, including concrete-over-metal decking
  • Standard (ANSI) fractional anchor: Fits most fixtures and installs with common drill bit sizes and tools
  • Tri-segmented clip: Each segment adjusts independently, increasing follow-up expansion should the hole increase in size as a result of a crack
  • High strength alloy clip on carbon steel anchors: this special alloy clip offers improved performance
  • Dual embossments on each clip segment: enables clip to undercut into the concrete thereby increasing follow-up expansion should a crack occur
  • AC193 code tested and approved to ensure outstanding performance in both cracked and uncracked concrete
  • 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 anchors performance if the hole increases in size because of a crack
