They have inferior surface compared to OEM nuts. I saw that some of the threads already had dents/dents from shipping. The threads are also not as deep as the OEM. I just hope they don't break. OEM ring nuts have a really great finish, but that's what we get when we buy cheaper parts. I've used 3 of these with 2 original OEM lug nuts just to be safe as I know I can definitely trust them and not this one (at the moment).
