I would give negative stars if I could. In fact, it's not even metal. It only lasted a week and a nut broke completely when I screwed it onto the stud and left it half attached. I had to drill out the rest. I did NOT hesitate if some people think so. Even if I did, it shouldn't have broken. Good metal would at least snap off the bolt. So I do NOT recommend these. Just pay more for higher quality nuts.
