Tolerances are written as a combination of a tolerance band, signified by an alphabetic letter (E, G, e, f, g or h, with uppercase letters signifying internal threads, and lowercase signifying external), and a tolerance class, signified by a number., ISO metric internal threads are identified by the use of capital letters for the tolerance position. ISO metric external threads are identified by the use of lower case letters for the tolerance position. As an example: M6 x 1.0 – 4g6g indicates a metric thread form “M”, “6” mm nominal diameter. The fastener is externally threaded as.

The metric screw thread is identified by the capital letter M, followed by the nominal diameter. Metric threads are measured by the distance between two adjacent threads in millimeters (pitch).
