these are t-nuts
nice review title, right? there's really not much to say about these. i used about 400-500 of them on my home wall and they all work just fine. the only thing i would say is that unless you spend a TON of time when you're initially putting them in, you're going to have a few that come out kinda crooked. just take a long bolt and carefully thread it in then pull on it real hard a few times. that will reseat the nut in the wall and allow you to easily screw on your hold. so far i've had no problems with these whatsoever.
