A good rule of thumb is to simply look at the normal direction that
the object spins. Almost always you loosen the attachment nut or bolt
in the same direction. For the nut or bolt to loosen by itself during
operation it has to spin faster than the object that it is holding
which is much less likely than if it loosened in the opposite
direction.

If you move the screw in the tighten direction, sometimes it loosens enough
for you to remove it. Covers both breaking a frozen screw loose and a
left-handed screw.
