Review on Z Threaded Hex Flanged Internal Threads Power & Hand Tools by Robert Fulce

I love these inserts later why 4 stars. The flange will hold them if someone pulls on them. Cherry is my wood of choice for furniture and the minimum thickness I've used is ¾ inch. I had issues with either the hole being too big and they didn't hold up well or being too tight and the wood cracking. Now I use a 2" hole that is ¼" deep, followed by a 1 ¼" hole that is 23/32" deep, a 1/2" hole that is 13/32" deep and a final 15/32" hole with a depth of 1/8". I dripped about two drops of superglue into the hole and drove it flush with a nut and bolt and washer to make sure the glue didn't get on the internal threads. I put a bit of glue activator in a spray can to set the glue on the non-outside threads. The only reason for four stars is that two of the three require threading or you will have trouble getting the screw in. After following the steps above, you can no longer delete the embed even if you wanted to.
