Note that the minimum thickness of a single member (in the "Bolt spacing and edge distance" section) may differ from the minimum plate thickness (in the "Capacity in bearing" section). Only the capacity based on the bolts themselves is computed: this calculator does not check the steel plates being connected for strength or serviceability.
