Our mechanical anchors are designed to install easily and securely into a variety of base materials, including concrete and brick to hollow and grouted CMU. They offer optimal performance even in the most demanding structural applications. The Strong‑Bolt 2 is a wedge-type expansion anchor designed for optimal performance in cracked and uncracked concrete as well as uncracked masonry.
  • 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
  • Standard (ANSI) fractional anchor: Fits most fixtures and installs with common drill bit sizes and tools
  • Suitable for horizontal, vertical and overhead applications
  • Made from zinc-plated carbon steel
