Strong-Bolt® 2 wedge anchor
The proprietary design of the tri-segmented clip has dual undercutting embossments on each segment, which enable secondary or "followup" expansion if a crack forms and intersects the anchor location. This significantly increases the ability of the Strong-Bolt® 2 wedge anchor to carry load if the hole expands as a result of the crack.

Head Stamp
The head is stamped with the length identification letter.

FEATURES

• 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.
