What bolt in what material?
I've rarely seen a bolt extractor work well but there are other methods...

Heat is best as long as it won't affect the surrounding materials, then impact tools then oils.
Hardened removing tools have their place but you have to be really careful as they're prone to snap off in what youre trying to back out making the whole issue a lot worse. Can you carefully drill and retap?

Or...
Place a washer over the broken bolt and weld it on filling the hole. Now drop a nut on the washer and weld that in a few spots around the outside. This has saved me with snapped bolts a few times.

Thanks for the replies I was changing the bolts that secures the castors wheels on one of my cabs and the head of the bolt just came away ive got the castor off but the rest of the bolt remains in the cab flush. I cannot apply heat as I will set the cab on fire

If you have the means (and I'm working off the top of my head so no idea how easy this would be), how about filing a slot into the end of the bolt to allow you to use a screwdriver on it?

Dremel with cutting disc might be able to do that, worth a poke. Or drill it out if you have access to the right kit.

Or as above with a hacksaw.
(Duh didn't read flush). Maybe a fragment of a hacksaw blade in a pair of pliers could cut a groove enough to get a screwdriver in with a bit of work. Slow and fiddly but it's an option if all else fails. Edited by Hemisphere - 21 May 2018 at 3:42pm |

If the bolt was fixed to the inside of the speaker cab with a t-nut, just hammer the remains of the bolt shaft through (this'll rip the t-nut out) and retrieve from inside the cab.
When the only tool you have is a hammer (well, no extractor or welders), every problem looks like a nail...
