The thread in the screw end is an extremely 'loose' fit and tends

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?
Sounds like a gentle squish of the end cap will do the job...
Thanks. could you explain to a novish 'squish' ? would i need to do
a degree course?
Depends how sturdy it is. If it's an AA-battery sized torch then
probably just a quick 'bite' or a gentle tap with a block of wood
would do the job. If it's more solid then a (padded) hammer could do
it.
The intention is just to make it very slightly out of round, so it
makes a good solid connection and can't rattle loose.
just ding the threads slightly and it will be tight and electrically
connected.
It's SO simple. just a tap with a hammer.
