The values shown in the chart are to be used as a mid-range guideline. If a bolt is torqued rather than the nut then the torque value should be increased to compensate for the additional friction – bolt should only be torqued if they are fitted in clearance holes. Nominal diameter is a more of a label than a size. The bolting standard will define whether the torque value is for a dry or lubricated stud/bolt thread.
