The class defines the Deviation (allowance) and tolerance of the thread. The coarse pitch is the commonly used default pitch for a given diameter. The class is written after the pitch. [2] Each thread is characterized by its major diameter, D(Dmajin the diagram), and its pitch, P. ISO metric threads consist of a symmetric V-shaped thread. ASME B1.1 For example, in the screw size 10-24, the first digit refers to the thread diameter, the and second digit is threads-per-inch (TPI).

Dimensions refer to the basic profile in accordance with ISO 68. [8] Fine and superfine threads also have a greater minor diameter than coarse threads, which means the bolt or stud has a greater cross-sectional area (and therefore greater load-carrying capability) for the same nominal diameter. It is common to designate metric fine threads with the capital M plus an indication to their nominal outer diameter and their pitch: The table below indicates the typically used finer threads up to size M 100.
