So I have a set of 32 and I'm not kidding when I tell you exactly half of them are deformed and spin horribly when I open them set the vehicle. The mids are clear and even. There is no transverse thread, but the outer shape is curved. So imagine a bent screw trying to get it out of a piece of wood. That's exactly what you need to attract those nuts. They are good and they look great. You can't tell by looking at them with the naked eye, but dude, they're tugging at your arm and it's annoying.
