I have never had this problem before, but if I did have one so tight I could not break it loose I would resort to drilling/Dremelling the nut down to very near the threads (without cutting into the threads of the insert), then a couple good hits with a chisel or punch in toward the center should break/deform the nut and causing it to release it's grip on the threads of the insert. Then buy a new nut.
I don't want to achieve immortality through my work...I want to achieve it through not dying.
