I tend to heat the bolt.

As far as I understand, bolts secure by clamping force and
that causes stretching along the length.

So if you heat the bolt, it becomes longer and the clamping force is
reduced.

So it's easier to remove.

I am curious, is it best to heat the bolt head itself or around the
bolt? Will Heating the bolt heat make it more prone to snapping off?

It seems heating a bolt would make it expand, making it tighter?

By the way on all the other bolts I removed there was no rust.
