Step down to 10-32 bolts, 1/4-20 is overkill for most FRC applications. Look up some of 973's work, they use a bolt pattern that allows for use of either a 10-32 Bolt or a 3/16" Rivet. Not a bad way to save weight.

I'd recommend staying away from Aluminum Bolts whenever possible. I've seen a few over-eager students give them a turn too many with a wrench and snap the heads right off.
