Rivets vs threaded fasteners

[Sperkowsky]

Our team forever has used nylocks and quarter 20 bolts. I tried to push rivets year but no one seemed to listen much and I was told that rivets can't be load bearing. We have about 150 bolts on our robot not even joking.

We have some cheap rivets and a couple of riveting guns around but can someone reccomend a good set from a place like grainger(has to have a ny state contract) we got our first 2 sponsorships ever this year so we have a little bit of spending money $1,100. We used about 900 of it on raw materials (aluminum square and rectangular tubing along with some 8020) but we have a few hundred for other stuff. Also stupid question does a new control system come every year in the kop.
