[Elecraft] Overtighted Case Screw Removal?

[R Thompson]

Rapid cooling of the screw may also help.  You don't need to go out and
buy some freeze spray if you have a can of dry air aerosol dust remover.
Turn the can upside down, using an extender tip that often comes with
contact cleaner or aerosol lubricants, and try to limit the spray to the
screw.  Turned upside down the can releases the liquid propellent which
is about as good as freeze spray.
