Minimum thread engagement metric
WebThrough holes are calculated without none-effective thread end and it is a prerequisite that the screw-end protrudes with two thread pitches minimum (2P) If an actual through hole … 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.
