A good rule of thumb is that the screw should drive through to about
half the thickness of the bottom piece. So a 1" thick piece being
screwed to a 2" thick piece should have a 2" screw.



Actually the rule of thumb is close to 2/3's of the thickness of the
bottom piece plus the thickness of the top piece.
OK, again assuming the 6" wall and 1/2" sheetrock, you're going to use
4-1/2" screws? The electrician and plumber aren't going to like you.

If the electrician's and plumber's work is impacted by the hanging of
drywall, then it's their own fault. They missed a step.

A few sheet-rockers found out the hard way not to cover Merv's
boxes!!! After a few weeks on a project using his magnet box finder
and keyhole saw to find the hidden boxes and numerous warnings he
resorted to the Estwing box finder. When they had to replace repair
about 14 sheets of drywall in a single house they learned how to cut
their drywall to keep the boxes open!!! (a subdivision of 35 or so
good sized homes)
