Dec 17, 1998 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, D (D maj in the diagram), and its pitch, P.ISO metric threads consist of a symmetric V-shaped thread.
