How to Work with a Stuck Bolt, from www.tips-tricks-tools.com

The best bet is to assemble nuts and bolts with lubricant so that
years later, they can still be unfastened. However, if you have not
had that advantage, and are faced with a stuck fastener now, here are
some techniques that may help:

Tap lightly but repeatedly on the head of the bolt or screw. This will
break the bonds of corrosion that hold the threads together.

Use Heat

Heat causes metal to expand, so if you heat the nut more than the
bolt, it will be larger. The hole in its middle will expand also, and
so it will be looser on the bolt. Heating also causes movement between
the nut and bolt, so that the adhesions will be broken. If the nut or
bolt won't turn when heated, try again once it cools.

Drill Their Heads Off

In the case of Phillips head screws, you can sometimes drill the heads
off, and then remove the remaining studs with a pair of Vise-grip
pliers.

Tap Sideways

Another technique that often works with screws is to drive against the
head of the screw with a chisel at a counter-clockwise angle. This
will create a slot in the side of the screw head, and you'll be able
to tap against the slot with tremendous turning force. Sometimes you
can even reuse screws that have been removed this way.

The Difference

By the way, do you know the difference between bolts and screws? Many
people think the difference is that screws are driven with a
screwdriver, and bolts have hexagonal heads. Not so. The actual
difference is that bolts engage a threaded counterpart, generally a
nut, while screws make their own threads.
