ISO Metric Fine Thread V

Compared to standard threads, a fine thread has a smaller pitch which increases the resilience. It is used e.g. for adjusting screws in measuring instruments because it allows for finer settings. The term consists of the letter M, the nominal diameter and the pitch, the flank angle is 60°.
