The difference between fine thread and standard thread
Webb1 maj 2011 · M10 is the nominal bolt diameter in the metric system, so its about 10mm (but always slightly less) 1.5 is the pitch, or distance between each thread, in mm. Sometimes specified as "coarse" or "fine". For an M10, 1.5 is coarse, 1.25 or 1 is fine. 30 means it is 30mm long not including the head. 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.
