Please keep in mind that the transport dimensions are absolute - unlike recent years which were a somewhat subjective perimeter. The allowance for bolt heads has specifically been ruled out (they do count towards the size limit). In the years before the switch to a perimeter rule, they had an inspection box that the robot had to fit in - bolts and all. It was an unbiased pass/fail test. I have seen teams grinding welds and replacing bolts with rivets to get that last 0.1 inch off so that they fit into the box.

Please design your robot to be at least 0.5in smaller than the transport limits to allow for tolerance of assembly and the inspection box.
