Opis:
I modified the bolt buster tension tester to test how much force the YABR (Yet Another Bolt Remover) can generate and it's a lot. It broke the bolt but I was twisting hard at 23.82kN or 5,354lbf! This is why you have to score, or aggressively spin, a bolt before pulling so the wedge doesn't get engaged because this can generate enough force to snap the bolt and make your existing hole unusable.
