I'm attaching something to concrete wall, can I insert it as illustrated in this image below? The washer would be sunk into the workpiece as shown and only half (the expanding part) of the sleeve anchor would be inside the wall. Is this an acceptable way to use sleeve anchors, or does the entire sleeve have to be in the wall for support? Image: https://imgur.com/a/wesKiVp

These things usually have a minimum embed distance. That will be the minimum length you actually need in the concrete. It should say on the package what that distance is.

If your workpiece is too thick, you will either need to sink the head in farther or buy a longer anchor.

Thanks for the answer! I found earlier that it's called embedment depth but couldn't find any actual examples on google after a while. No box, they sell them standalone where I got them (and any answers from shop would be 'go with the flow' type attitude rather than to look for manufacturer answers). Spent forever making this drum stand and now stuck on what I assumed would be the simplest part :D

Just use longer bolts. Anchors are engineered to be fully embedded.

Thanks! I got longer one with two sleeves. Guess I will shorten both bolt and second sleeve for the right length to not stick out of piece and fully embed the (first/deeper) expanding sleeve. Sounds legit this time?

Don’t know why you want to put a sleeve in the part you’re attaching to the wall. It seems overly complicated to me and difficult to attach.

Makes sense, will use longer bolts with washers. Thanks for your input, much appreciated!

As has been said, the anchor is designed to be fully embedded in the wall. Cutting the anchor will likely change its ability to support the designed weight, as you will be changing how do anchor expands.

Thanks, took me a moment to wrap my head around it. Second sleeve just covers the top half of the bolt and doesn't expand. Either way, am leaving it out.
