Blue Spot Tools22307 3/8" Impact Stud Extractor, packaging may vary

Very simple technology but worked a tread on head bolts on my bmw and a few stubborn broken Studs

These two studs with an inch left to grab hold of were too much and it failed to break them free - however, there is always next time and feels like a capable tool.

Does exactly what it says on the tin. Removed 2 broken studs from a motorcycle front fork with ease. I had heat standing by but didn’t need it.And it was cheaper than many unknown makes.Blue spots lifetime warranty is very good.

You dont know how good this is until you need it. recommended

Bought this as I had 3 stuck studs in my rear wheel hub on the motorcycle. Tried many different things to get them out but no joy. Seen this was only €15 on amazon so thought I'd give it a try. Had them all out in 10 minutes.Not sure about the longevity of the unit but for the price I can't complain.One thing I would advise is to get a long reach breaker bar to use with this tool. Initially I tried a standard socket set but it wouldn't budge, then I tried the breaker bar and it moved effortlessly.

I found this ok and it removed two broken bolts from my car engine, however the third it would not grip - it looks like after removing two the tool has become worn. The third was removed by welding a bigger bot to the broken one....

It did the job but broke unfortunately after using it three times

Worked well on some large 10mm studs but would not adjust tight enough to get any purchase on some 6mm stud i needed to remove (Honda manifold studs). Very rough and notchy to adjust to.
