What size are Servo screws?

I have some airtronic 94102z servo. What the screw size for the servo horn so I can connect it to stuff and also the screw size for the center of the servo?  I wasn't sure if all servo were pretty much the same except for the micro of course.  I did manage to find some for the center which are 4-40x1.  They seem to be ok so I'm sure if might work, but I want to find out from the experts out there.  Also where would be the best place to get screws for servo horns locally.  Thanks for your help.

I thought you were after mounting screws. This is where you have to be more specific. Yor title should have mentioned servo horn screws or something. As for replacements. I'm told that some online hobby shops sell bags of mixed screws.
