          Used these to anchor a new wall to the cement slab in my garage. They were easy to install and hold the sole plate tight to the slab. I would buy these again should the need arise.

          they work great
          Needed to anchor a wall to the foundation and these were perfect, drilled the hole and blew it out, hammered them in and tightened. All the sleeve anchors are holding great, none of them slip or loose.

          I used these (overkill I know) to mount a 77”...
          I used these (overkill I know) to mount a 77” LG OLED TV into my Florida home walls. They are drywall on fitting strips over concrete block, so the 3” length helped assure me I was getting sufficient depth into the block. Had to drill out my Sanus TV mount holes slightly to about 7/16 to accept these anchors but installation was fairly easy. Used Milwaukee 1/2” x 6” 2-cutter SDS-PLUS carbide drill bits to drill 10 (yes, I used them all) the holes for the anchors using the template from the TV mount manufacturer. I then removed the washers and nuts from each anchor and inserted the anchors into the holes. Careful: some may slip too far into the wall. If this happens and you can’t get them out, do what I did and use a combination of a dental pick and magnet to hold them. I then placed the mount over the holes. Inevitably, the holes were perfectly aligned. Use a dental pick to push or pull the anchor bolts to one side to get the mount installed. Then, tighten and voila!

          Shears off too easily
          Pay attention to the TORQUE, these (esp. the thinner/shorter ones, e.g. 5/16" x 1-1/2") shear off much too easily. LUBRICATE the threads before tightening if installing in hard concrete; back off after each turn when you feel resistance. If the threaded bolt DOES shear off, hammer the bolt part back into the hole just enough to expose the inside of the metal jacket; grab onto the neck of the jacket w/ a pair of needle-nosed pliers and wrestle it out, then also pull the threaded bolt out.

            Good anchor but ... Drill end strips easily.
            These bits are nice and easy to use but the end you screw in is made of super soft metal. Strips super easy. Difficult to keep a bit in.

              Easy to use, works well for proper applications. Just be sure to drill the holes to the proper depth, because if very difficult to remove the anchor bolt after hammering it in.

              Solid sleeve anchors that provide a good hold.
              I installed two of these in cinder block wall (in the area of the block sidewalls and mortar and they held well. I drilled a 1/2" diameter hole and the fit was a bit tight, I would recommend a 9/16" bit, especially if you are screwing the bolt out more than an inch. I used these to secure an old 2x4 shelf bracket to the wall and they worked great.

              not good for taller posts
              Used it for installing a shade sail on my backyard and it was a nightmare. 1- First of all, this product is hard to install for a novice home project guy like me. The hole should be perfect. If it's too tight, then you can't penetrate it fully and guess what? It's almost impossible (at least with the tools I had) to pull it out. So, you have to make another hole and use another anchor. 2- After having several failures, I made the hole a bit looser - which looks perfect. But after installation, with a couple of relatively heavy wind, it got out of the hole and the post (wooden post about 8') became very unstable. 3- even it was my fault, the instruction was extremely bad. I don't think even the picture is similar to the real product. Not happy at all.
