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

I am going to put a bolt into wet concrete to tie to a 6x6 post base https://www.homedepot.com/p/...

Answer

It is up to the Designer to specify the anchor bolt type, length and embedment based on concrete strength, bolt location/spacing, local building codes, etc. I will point out that wedge anchors are installed in existing concrete. Please feel free to contact our Engineering Support Department at 800-999-5099 to discuss further (with more information, they can share possible anchor options). Thank you!

Provided you drill a hole in something that is hard, they work perfectly. If you drill into a block wall with air spaces, they don't work well so you need to find an area where you can insert them and then drill off the extra threads.
