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.
