The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. Each thread is characterized by its major diameter and its pitch. ISO metric threads consist of symmetric V-shaped thread.
Charts for the allowed range of pitch, major and minor diameters for classes 6H and 6g. The values are calculated from the definitions of ISO 965-1. They have limited use since they provide data only for the default classes.
The following table chart defines standard metric external thread size M1.6 to M18 per. ANSI/ASME B1.13M-1995. These thread sizes and classes represent bolts and screws, as well, as other standard external threads.

Learn about the common thread types, geometry, and dimensions for different standards, such as ISO metric, Unified, and American National Pipe. Find out how to measure and specify thread size using pitch, major diameter, minor diameter, and other parameters.
Designation. A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by a dash or sometimes the multiplication sign, × (e.g. M8-1.25 or M8×1.25).
