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

Wrap a few turns of Teflon pipe thread tape around the male threads so
that the looseness is removed. You might have to rewrap frequently,
depending on how much use the flashlight gets.
Another suggestion is to cut a gasket out of a sheet of very thin
rubber or vinyl sheet, lube it with silicone grease and wrap the
gasket around the threads.

won't that insulate it? ...
If it IS a real MagLite, OP is mistaken about it being part of the
circuit. You can actually take the nose off and use it as a base, and
use the flashlight as a candle. (leastways, on the pre-LED versions) I
suppose there are some knockoffs that use it as part of the circuit, but
I have never seen any. Flickery light is almost always due to an
internal spring getting wimpy.

(Note- even on a full-size Mag, the side switch is repairable. A pain to
get it out, but repairable.)
