I'm not saying it doesn't work, it just doesn't work for my application. I have Gorrila locknuts. The top of the nut is threaded. It turned out to be a lot for an outlet. I tried and tried to get the nest to bite but it didn't work. One socket was too big for my Sierra Lugs and the other didn't bite. I'm pretty sure they will fit different types of locknuts (I've watched a few youtube videos that prove they work) but not the gorillas I have. I sent the package back and they gave me a full refund. The product received 2 stars. because it didn't work on my app, 5 stars for my money back.
