ISO metric screw thread - Wikipedia
Sep 15, 2013 · The design principles of ISO general-purpose metric screw threads ("M" series threads) are defined in international standard ISO 68-1. [2] Each thread is characterized by its major diameter, D (D maj in the diagram), and its pitch, P. ISO metric threads consist of a symmetric V-shaped thread.

Thread Pitch Calculator > Formula > Example
The formula for calculating thread pitch varies based on the measurement system: Metric System: Pitch (P) = Distance between adjacent thread crests Imperial System: Pitch (P) = 1 / Threads per inch (TPI) For metric to imperial conversion: TPI = 25.4 / Pitch (mm) For imperial to metric conversion: Pitch (mm) = 25.4 / TPI. A bolt has 16 threads ...
Both DIN and ISO standards for metric threads ignore the pitch callout on coarse threads. For example, a thread diameter defined as "M12" indicates a coarse pitch (M12-1.75).
