hi i need 4 mounting screws on the sides of my pcb board and i was wondering what are good dimensions for the screw holes.

something like a .1" pad hole with .046 hole and hole tolerance +-.004
 
I tend to make screw holes a bit on the large side especially if the board has to be indexed to something else in the box, just so you have a bit of play in case everything does not line up exactly...for example pc mount xlr connectors that go through holes on the back face of the box.
So yes, for a #4 screw I'd use a .125 drill hole....that's just me though :wink:
