Product Details

Code listed for cracked and uncracked concrete, and masonry applications, the Simpson Strong-Tie Strong-Bolt 2 wedge-type expansion anchor is an optimal choice for high-performance even in seismic and high-wind conditions. Dual undercutting embossments on each clip segment enable secondary expansion should a crack form and intersect the anchor location; this feature significantly increases the ability of Strong-Bolt 2 to carry load if the hole expands. The Strong-Bolt 2 is available in carbon steel, Type 304 and Type 316 stainless steel.

  • Qualified for static and seismic loading conditions (seismic design categories A through F)
  • Suitable for horizontal, vertical and overhead applications
  • Qualified for minimum concrete thickness of 3-1/4-in, and lightweight concrete-over-steel deck thickness of 2-1/2-in and 3-1/4-in
  • Tested per ACI355.2 and AC193
  • Size: 1/2 in. x 7 in.
  • Made from zinc-plated carbon steel

Q:What is the recommended spacing on a ledger board with an 8? span?
by|Jun 3, 2023
1 Answer
Answer This Question

A:  Hi Mccart, this is Colin from Simpson Strong-Tie. We do not have literature for the Strong Bolt 2 in a ledger application. A better mechanical anchor option would be our Titen Heavy Duty Screw Anchors in a mechanically galvanized finish. Please see our website at www.strongtie.com. Type in keyword "THDMG" in the search box. The search results will lead you to our documentation for using this product (and spacing) in a ledger to concrete, or ledger to GFCMU application. If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you. Thank you.

    Answer This Question

    A:  Hello Symantha, This is Colin from Simpson Strong Tie. I am not sure I understand your question and do not know what a wind well is. I suggest you visit our home page at www.strongtie.com and enter Strong Bolt 2 in the Search strong-tie field, scroll down to Literature and open the Technical Engineering Bulletin TEB-A-STB222 for specific design information on the STB2 series. If you need more information or have additional questions, please contact the Simpson Strong-Tie Customer Service team at 800-999-5099. We look forward to hearing from you.​​

        Q:Each bolt how many pounds can it hold for a AC Unit suspended below the ceiling the unit is about 150lbs
        by|Jul 2, 2018
        1 Answer
        Answer This Question

        A:  There are different factors that affect the capacity of an anchor (i.e. what it is being attached to, embedment, etc.) and we're not clear that this would be the correct product for you. We would suggest contacting us with complete information on the application to discuss possible anchors - 800/999-5099. Thank you!

          hold well. don't drive the bolt into concrete without the piece you are anchoring in place. even with the nut properly situated, the threads got mangled and we had an awful time removing and rethreading the nut.

          They were very easy to go down into the hole that was drilled 1/2 hole was required. The bolt locking system would not hold into the concrete. Would never use this system again
