"Seized and rounded bolt/guide pin for brake calliper needed removed. Bought these thinking I'd have a half chance of loosening the bolt, as I'd already flattened the teeth on an older set of grips I had. No need to worry with these grips in your toolbox! A few hammer taps to the grips after securing them to the rounded bolt and it started to come loose! Furthermore, an inspection of the teeth after the work showed that there was no damage. I'd recommend these grips to anyone that has to deal with a seized nut/bolt. Decent price for a quality tool that should last you for years.
I don't usually post reviews, but felt compelled to after this successful job. It meant the difference between being on, or off the road until payday in a fortnight. I would then have to have paid a garage for a job that I can normally do in an hour."
"bought these after my droplink was seized at back of the nut, got the nut of in under 20mins, I have only gave four stars for performance due to the teeth of the grips beingflattened due to the force I needed it to grip,but cant complain for less than a tenner."
