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 ( Dmaj in the diagram), and its pitch, P. ISO metric threads consist of a symmetric V-shaped thread.

ISO 261 and 262 Fastener Diameters. For each size bolt or screw and type of head, there is a corresponding size driver prescribed by Acument, the designer of the Torx drive system. As of 2018, there are no ISO standards for hexalobular drive sizes.
