Stuck hardware occurs when a bolt or nut got corrosion between the threads and they don’t want to budge. One of the biggest frustrations when unloading vehicles for restoration, or even improve, the dreaded is seized or stripped the bolt. How to remove a stripped bolt head is very easy to do.
Many times this leads to breaking up the bolt and drill and retap should continue or try to remove it with a bolt extractor.

How to remove a stripped bolt underway to deal with getting this sucker taken without damaging valuable section they are in. See how to remove a stripped bolt here.
How to Remove a Stripped Bolt
Heat. By doing this the bolt extends because of the heat, and when it’s cold it will contract thus breaking corrosion between the threads. A similar method is to heat the area around the bolt to make a hole that is threaded into really expand and open a little so that the bolt fits a little loose and can be threaded out.
Rock the bolt. Take a ratchet and loosen the nut/bolt a little to get a little tension behind it again, then go back to the other direction and turn it almost to where you started, before loosening a bit further from the last time. When you open some hidden threads, you want to spray penetrate some of those threads so penetration works his way back into the hidden threads.
Blunt Impact/Force. Work on the theory of liberating the corrosion bond between threads by vibration or impact. Working occasionally on the bolt lightly seized, but not a winner 100% every time. But keep in mind it can be combined with many other methods to help make the job easier.
