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.Simpson Strong Tie Co., Inc.
