Customer Reviews

Irwin bolt grip
Most tools of this type are overrated, and I was sceptical when I saw this one advertised. However, I ran into a situation at work where I had to remove some badly rusted and rounded over bolts from the exhaust manifold of a piece of earthmoving machinery, and none of the standard methods worked. After trying for 3 hours, I finally bought a set of Bolt Grips. They really worked. I had all 3 bolts out in less than 5 minutes. I am sold on these things.

seems a little expensive but well worth it
i was under my truck for 3 hours with pb blaster and vice grips trying to get off rusted, rounded off axle bolts. bought a set of these and i was done in 15 minutes. a MUST HAVE for any home mechanic with an older car.

Does the job well.
Comparing this to the bolt out set that I purchased from ACE hardware, this set was wonderful. The ACE hardware set did nothing to my stuck bolts. The irwin set helped me remove the bolt almost as if there was nothing wrong with it.
