From complex infrastructure projects to do-it-yourself ventures, Simpson Strong-Tie offers a wide variety of anchoring products to meet virtually any need. 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

Questions & Answers


Are these anchors made in USA?

Asked by Bobby June 12, 2020

Strong-Bolt® 2 Wedge Anchor, STB2-75512, is not manufactured in the U.S.A. Thank you!

What is the minimum embedment for this wedge anchor?

Asked by Florian May 18, 2020

The minimum embedment depth for the 3/4" Strong-Bolt 2 is 4 1/8", as referenced in ICC-ES ESR-3037: https://www.icc-es.org/wp-content/uploads/report-directory/ESR-3037.pdf. Thank you!

How much weight can these hold?

Asked by mlehman6 March 15, 2020

There are many factors involved in determining the allowable load (what is the application?, what is the concrete strength?, what is the spacing?, tension or shear capacity?, etc.). Please feel free to contact the Engineering Support Department at your regional Simpson Strong-Tie office (800-999-5099) for further assistance with determining the appropriate product for your application. Thank you!

how many PSI can each one hold? with this stretch with 3000 PSI? using it to hold 2 post car lift...

Asked by doe January 7, 2020

These are the anchors most people use for car lifts. I recommend cutting the floor and pouring a deeper footing unless you already have a thickened slab. Hope this helps.

Asked by Tammy September 3, 2019

Asked by Glenn February 2, 2018

Bolts are awesome. BUT as a home owner, they are extremely difficult to install. Drilling the appropriate size hole requires an impact drill and multiple drill bits. If you do not own these, you have to rent the equipment and the drill bits.
