In general, our team decides on what fasteners we are going to use for that year, and then orders a large amount of them form McMaster. We always have left overs at the end of our season which are sorted and kept in containers in the shop closet. When prototyping, we use the leftovers, but when assembling the robot we use the new bolts/screws/rivets. In general, we use socket head cap screws (SHCS), but also use button heads, low clearance, or even counter sunk bolts/screws when clearance is an issue. For rivets, we pretty much only use 1/8" blind aluminum rivets.

Last year specifically, we used a standard size of 10-32, of varying lengths. Occasionally we used #6 and rarely used #4 bolts. From what I've seen #10 and 1/4-20 are pretty standard in FIRST.
