Since cutting bolts is not recommended, becuase it makes them alot harder to open and close, you better use small bolts to begin with.
Thread a nut on before you hacksaw the excess off, then unthread it off afterwards. It may turn off pretty hard, but it will clean the threads up significantly.

Since steel is way denser than aluminum and teams often tend to use much larger bolts that necessary, this is probably the first course of action on Thursday when you try to meet weight.
