It looks like every servohorn that I see online has predrilled holes all over them, whether it be on a 4-arm cross or a circle or a gear or whatever. Are there special pins that are supposed to fit in there, or if not, what kind of screw is supposed to fit in there? Home Depot, Ace Hardware, even RadioShack doesn't carry screws that small, as far as I can tell. How are you supposed to use those?
Thanks.
