I have one of those small LED pocket torches (flashlight). To turn
it on and off, I have to screw the end up towards the bulb end to
compress the contacts against the battery.
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 tap the threads with a hammer to ding them up a bit,just enough to make
the screw go in tightly.
