Which size bolts to use with electronics?

[TheHolyHades1]

For various electrical components such as the victors, PDB, cRIO, window motors, etc, what size bolts do you use? I seem to remember 10-32 as the size most of the electronics use (and 1/4-20 seems to work for the rest), but I'd like to just make sure that I'm ordering the correct components right now.

Could you please tell me what size hardware you use to mount your electronics to the various boards on your robot? (Alternatively, if you don't use bolts, any guidance towards alternative mounting methods would be great).

Thanks!
