I may have to do that (I assume you are talking about set screws correct?), I ruined my first set of coils because I tightened the screws too much and they cut the kanthol, so the second attempt I did hand tight then less than a quarter turn, but they still seemed a little loose to me, even when I snug them back down it seems like they work their way loose again.
