Irwin Bolt Grip Nut Remover Set Expansion Set is rated 4.3 out of 5 by 49.
Rated 5 out of 5 by from Great - just the solution you need Together with the expansion set, this fits pretty much every stuck bolt you'll need - the sizes adapt a little as they are flared, so the missing sizes are covered by the set, honest!

Rated 5 out of 5 by from Does exactly the job you need Life-saver. Don't worry about the odd sizes listed (there's no 12mm for example...) as the flared shape means they will fit sizes around the one specified. With some WD40 penetrant this freed up two badly rounded nuts on my son's motorbike which were not moving any other way. A bit pricey but once you've got them, they are there for life.

Rated 5 out of 5 by from sump plug was a breeze The only nut remover set i could find that was big enough to remove a very rounded sump plug off of focus st mk2. good quality and no damage to the removal nut after use either. Very happy i didn’t need to cut the nut off.

Rated 5 out of 5 by from Lifesaver! Used to remove a stubborn/rounded brake caliper bolt, did the job perfectly at 1st attempt, quality little kit to keep in the tool box. Only minor gripe was the set i bought had obviously already been used to remove a sump plug judging by the amount of engine oil inside the case.

Rated 5 out of 5 by from Impressive. Tried to remove a rusted bolt from car chassis using wd40, heat, impact gun etc and rounded nut off. With a bit of heat and 1 of these dudes on a rattle gun it came straight off. Just brilliant

Rated 4 out of 5 by from Caliper bolt removed Bought base set to remove damaged T50 Caliper carrier bolt from rear Peugeot brakes. The 16mm (largest) fitted a treat (was worried they would all be too small). Hammered (gently) the Irwin socket onto the bolt and managed to extract a heavily over thread locked bolt with a breaker bar. Zero damage to Irwin socket, but need to replace Caliper bolts. Would have given 5 star, but as these are 3/8 sized I had to buy an adapter to fit my (and most other I suspect) breaker bar.

Rated 1 out of 5 by from not up to the Job i bought this after reading the good reviews to have the 16mm one shatter very disappointed.
