A. Ott: Had some chair threaded inserts get damaged and stripped out. Replaced the old inserts with these and a little Gorilla Glue and they're working great! Nice, solid inserts!

Pete: Poor manufacturing quality on a sofa which required some adjustments. These inserts did well and the sofa feeds are now stable as they should have been in the first place.

Chris H: I used these for two projects so far. I wanted to add castors to a workbench, to raise it and make it mobile at the same time. I took a couple of pieces of 2x4 cut to the width of the bench and inserted 16 of these, 4 per caster. I was then able to screw the 2x4s to the bench and then bolt the casters to the bottom of the bench. Very secure. The second application was securing a mailbox. I wanted blind fasteners but I didn't want to have to rely on wood screws. I cut a piece of 1/2" plywood to fill the gap under the mailbox I chose and drilled it to match the mounting points and added inserts. I screwed the plywood onto my mailbox post and could then bolt on the mailbox. it is so much easier to use the bolts than to try to start screws while reaching to the back of the mailbox. And the mailbox is much more secure. The flanged bolts I used won't pull through.

T. Bennett: They’re extremely difficult to put in straight.
I wish there were instructions for what size drill to use. Luckily another reviewer mentioned 3/8” worked. I never would have figured that out just by eyeballing them. And the only reason 3/8” worked for me is because I rocked the drill bit side to side a little at the end. Which probably contributed to them going in crooked, but at least they went in.
I imagine if I had a drill press and a more adequate size drill bit that it would have worked better.
If you look, the top of these are wider than the bottom so the rocking was necessary. 1/2” would have been too big but neither of my drill sets have anything between 3/8 and 1/2.

It’ as painful as it is that many went in terribly crooked—I’m a perfectionistic as they come— for my application it doesn’t matter, only makes me cringe every time I look at them. I can live with that I guess. It’s user error, just warning you that they might not be as simple to install as you would think.
I used them to make wood woof’em stick toppers to screw onto my pie iron handles so that I don’t have to haul around a third type of stick in our camping gear (pie...
