It is common to designate metric fine threads with the capital M plus an indication to their nominal outer diameter and their pitch:
M size x pitch
Example:
M 10 x 1.5
The table below indicates the typically used finer threads up to size M 100. Note that the ISO 724 standard specifies threads up to M 300.
