Another trick that works very well for me is to
try tightening the bolt
slightly. Put the tool on, turn it clockwise (assuming a right-hand
thread), then try turning it anticlockwise again. About 95% of the time,
the bolt comes right out.
When we work with stuck valve caps, etc. on brass instruments, rather than
apply force using something like a strap wrench, what works better is a
tangential blow with a hammer (rawhide head in the case of brass). The
concussive shock works where a steady torque does not--and the chances of
stripping threads or shearing bolts is much reduced.
When working on my car's suspension and drivetrain, I tend to use a
combination of penetrating lube, heat and concussion.
