Hello,
Can someone explain to me why using heat makes it easier to remove a bolt that is rusted? I know that the iron and oxygen forms iron oxide. That means mass would increase in the bolt thread area. Heating the bolt would make it expand. Does the heat just cause the iron oxide to be compacted, making more space again? Any thoughts would greatly be appreciated.
