I have one of those small LED pocket torches (flashlight). To turn

The thread in the screw end is an extremely 'loose' fit and tends to
'unscrew or scew up' when it sits in the car glove compartment for a
while.

Is there a way to *stiffen* this 'loosness' in the thread, without
reducing
the electrical conductivity?

It needs to make good electrical contact for the torch to work, so I
guess
that rules out putting a dab of wood glue on the thread? Thanks
for any
advice.


run a rough file over the threads

Or insert a piece of dowel, then crush the threads a little with a hammer.
