I dremeled the tip off when a fender bolt got focked. It was a waste of time though, it takes too long for me. Then i just vise griped the screw out - if you do this, screw it down, not up, I stripped the lower threads, so it wouldnt go out all the way. Then i screwed it going down too. So imo, a big waste of time. Just dont strip thebolt in the first place
