threads having the ISO basic profile for triangular screw threads. Data for 1,0 mm to 300 mm diameter threads is tabulated and Appendix B is included giving the information necessary to calculate the limits of size for exception to the tabulated data.
– Metric screw thread, fine series, are designated by the basic diameter, preceded by the profile letter M and followed by the pitch separated by an x-mark and then by the tolerance grade, e.g. 6, and the tolerance position, e.g. H. Example: M10 x 1,25 – 6H.

The Ulitmate Metric Screw Thread Resource: Basic Dimensions, Classes, Tolerances, Formulas, Charts, and Explanations
In our metric screw size chart above, metric thread size is denoted by a series of numbers and letters that encapsulate various dimensions including the major diameter, thread pitch, and thread type. The most common system adhered to is the ISO Metric Screw Thread, where designations like M6x1 signify a major diameter of 6 mm and a pitch of 1 mm.

Thread Size Measurement — Two primary methods, length and weight. Weight — In weight measurements, higher numbers reflect finer or lighter threads. The “weight” of a particular type of thread refers to the length of a given weight of thread. Dividing the length of thread by a set weight derives the exact measurement of a thread weight.
