You don't need the nut, really (and its rather abnormal on Schrader valve tube) -- a lot of people just throw it away. The point of the nut is so that the tube's stem doesn't go into the rim when you're trying to inflate the tube and the stem doesn't move around when you're trying to pump the tire. Note that the tube can only go significantly into the rim ...
I loosely tighten before inflation- just to stop the valve from disappearing whilst inflating it. After inflation, it needs to be finger tight- else it will rattle on the rim. This is probably the number one reason why most people don't use them- the slightest looseness here will be very noisy (especially to deeper section wheels).
