Kim, we went round and round on this here:

As it stands now, from my understanding of Team Updates 6 and 7, you are allowed minor protrusions in your FRAME PERIMETER, and they do not count in the definition of it. But remember that FRAME PERIMETER is defined to be in the BUMPER ZONE.
Protrusions that extend beyond the vertical projection of your FRAME PERIMETER outside the BUMPER ZONE are disallowed except for the exclusions in <G30>. Bolts, axle ends, etc are not allowable exclusions.
So the way it sits is a bolt that holds your frame together within the BUMPER ZONE is OK. A bolt that holds your lower frame together or a bearing that holds your axle, is not excluded. The only effective way to get around this is to make sure your frame dimensions in the BUMPER ZONE are the largest dimensions of your robot.
