I also check the screws often, especially on bass-pitched wind instruments.
The screws are the first things I suspect when my bass sax starts rattling
and making extraneous humming noises. The vibration of air inside that big
pipe can be felt on the outside very easily. The vibration works things
loose.

Once I heard a high-pitched whine, a sympathetic vibration on certain notes,
that turned out to be coming from the place where one of the long key-rods
screwed into a post. Tightening the screw got rid of the noise. I wonder if
ignoring something like that might strip the threads or otherwise do some
damage eventually, because that sound came from metal rubbing on metal --
same principle as a grasshipper rubbing its legs together, maybe. The
thought concerned me enough that I started keeping a jeweller's screwdriver
of the right size in the bag with my reeds, cork grease and whatnot, so that
the need to hunt for a tool won't tempt me to act lazy about tightening
things up "later.".
