To Loosen a Stuck Bolt
To loosen a stuck bolt, use heat, oil, and tapping. Apply enough heat to make the entire bolt expand, about a minute or so for an average sized bolt. When the bolt is cool enough to touch, squirt it with penetrating oil. Tap the head of the bolt a few times with a hammer, allowing the oil to penetrate and the threads to loosen. Then remove the bolt.
