WebbThe pitch diameter is the diameter at which the thread tooth and the thread space are equal. To accurately measure the pitch diameter requires an optical comparator or thread wires. The optical comparator is the easiest to use as the measurement can be directly made and no mathematics is necessary. WebbExplanation: Pitch: Designated by “X P“.For example, M8 X 0.75 means an 8 mm (0.315″) thread with a pitch of 0.75 mm (0.03″ or 34 TPI).If the “X P” is omitted, the pitch is defined by the Coase Pitch Series according to ISO-261. Number of starts: Designated by “Ph”.For example, M8 X Ph2.25P0.75.In this case, 2.25 mm is the lead, and 0.75 mm is the pitch.
