Rating: - Alden Grabit Broken Bolt and Damaged This Grabit tool worked as advertised. Just follow the instructions and remove the damaged screw like it was removed from butter. Highly recommend it. Rating: - Junk This item is a piece of junk. After numerous tries to actually remove damaged screws i threw them away. Rating: - Work or Not Thought these might be better than easy-outs but are not. Broke on first bolt broken in aluminum transmission, drilled it out and reversed bit. Sprayed the bolt and it was tight in there, kept trying for three days a little at a time, finally the bit broke. Wasn't using to much pressure on it either. Might be good for broken screws but not on bolts, even small ones.
