The complete designation of an ISO metric thread includes the basic designation [the letter M followed by the nominal size in millimeters and the pitch] followed by the specification for tolerance class. The tolerance class designation includes the symbol for the pitch-diameter tolerance followed by the symbol for the crest-diameter tolerance. Each of these symbols consists of a number indicating the tolerance grade followed by a letter indicating the tolerance position. A dash separates the tolerance-class designation from the basic designation. When the pitch-diameter and crest-diameter tolerance symbols are identical, the symbol is given only once....
