In case you were curious: the AGD (American Gage Design) protocol, for the purpose of standardization, specifies many of a dial-indicator's characteristics, among them the dial diameter (Group 1 is 1-1/2; Group 2 is 2; and so on, up to Group 4), a stem diameter of 3/8, and yellow dials for metric indicators.
