The only way is to somehow get the bolt turning anti-clockwise. I think there's a trick for this but I'm not sure what it is. Hopefully the threads on the thru axle aren't damaged and it's only the hex but that's rounded off. Other option is to cut the crank off at the bolt if you don't want to save it! | |

Also, there should be 2 hex bolts on top of each other one a smaller right hand threaded one and a larger left hand threaded. Are you turning the smaller internal one? If you remove the larger external one, you should be able to see what's going on with the internal one a little more clearly, ie. is the head still attached to the thread. | |
