*Too much heat will destroy the temper of the bolt. Important bolts (brakes) should then be replaced with new as the untempered one if reused could fail. | *Too much heat will destroy the temper of the bolt.

Heat the '''nut''' with a torch until red hot, cool the bolt with a good shot of spray-on rust remover then remove the nut while still hot. Heating the nut thermally expands it, while the rust remover (which is a refrigerant) thermally contracts the bolt. Be careful and use gloves as the nut and your wrench will be hot. | Heat the '''nut''' with a torch until red hot, cool the bolt with a good shot of spray-on rust remover then remove the nut while still hot.
