## Description

Product description

Review: Work good, error on buying a little longer than you think - Worked great. In hindsight I would have bought longer ones. I torx head screw driver works better than the tool they sell to set them. Buy the arrow head concrete bits and everything will work perfectly.
Review: Great Drop-In Anchors!!!! - These were just what the doctor ordered. I needed to install a tent on my driveway and didn't want the tent to blow over with the wind. On dirt, I would have hammered some steaks in, but on concrete, I didn't want to use Tapcon Concrete Screws. I wanted something I could put in and take out without continually making holes in the concrete or worse, breaking it up. These went in great. Drilled, dropped them in and then screwed the included machine screw and they held the tent up under heavy winds. Perfect for the application!.

### ⭐⭐⭐⭐ Don't forget the drop-in anchor setting tool
*by W***. on May 14, 2025*

I purchased the Stainless Steel and installed two behind a water spigot whose hole was drilled too large by the person who installed it. A little PC concrete plus these anchors seem as hard as the brick I attached them to. I bought a couple of stainless steel screws locally and now my water spigot is held firmly to the brick, but I can still remove it within seconds if needed in the future. Great product! To install these easily, you needed a drop-in anchor setting tool. I didn't realize this until after I received them, so I had to delay my project a few days while I ordered and waited for the tool to be delivered. I highly recommend you guys sell a package of these with the tool, too! It would only cost a few more dollars and allow a new customer to get everything they need at once.
