WebThe 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. In the plane of the thread axis, the flanks of the V have an angle of 60° to each other. WebTorque has been converted into ft/lbs by dividing the result of the formula by 12. All calculations are for Coarse Thread Series (UNC). Grade 2 calculations only cover …
