Worked perfectly to secure an outside door threshold to a concrete slab once you drill the hole.

Easy and solid. I fastened two X fours to a concrete wall for shelves, they are as solidly fastened as I could ever imagine.

Make sure you get the hole deep enough because it won’t come back out ?

Did not hold flag mount on brick wall. Lasted about a week and worked out. My guess is that brick was too soft for these. Shame since they were almost $2 each.

where to start
I drilled the 3/8 hole, hammer down to the desired depth and try to take the nut off! The bolt spins within the casing. (not easy) Then when I took the nut off the bolt slid into the casting!! What's up with that! Then I had to fish out the bolt to put the nut on. All this while making sure I did not drive them in to far for my metal bracket, once placed over the anchors to be able to have enough treads to get a washer and a nut on!! Some anchors worked while others did not.

Used (4) of these to hang our Mantel Mount TV mount from a brick wall. Works great. Don’t overtighten however, bolts will break easy.

Good products. Secured tightly to the stucco wall. Just didn't have the exact length that I was looking for. Thus I had to use the next longer one which affected the esthetics.

Used these to secure a gate latch to a cinder block wall. A bit of overkill, but I wanted them totally secure.
A useful tip: If you are securing something with more than one bolt, get the first one positioned and then add each additional one.
It is important to tighten each one as you install it, even if with just the supplied washer under the supplied nut. Tightening it in the hole as you go secures the bolt by wedging it into the sleeve. Then you can remove the nut and washer and put the thing you are installing over the bolts and secure them with the washers and nuts.
If you insert the sleeves but don't tighten the bolts into the sleeve, you run the danger of having the bolts slide into the sleeve to where you can't get at them.
Another thing to be aware of: The bolts are long enough to secure a flat piece to the wall, but if you are trying to attach something thick, like a metal tube, the bolts are not long enough. (Perhaps you could use a longer bolt from a longer anchor with the short sleeve from shorter anchor.) The bolts are not standard bolts since they have a flared end that pulls against the end of the anchor sleeve to expand the sleeve and tighten it into the wall when you tighten the bolt.
Anyway, these are great for securing something into concrete or cinder block.
