馃敼A shot video with a clear explanation of the thread term "Thread Lead". The lead is the linear distance the thread travels due to a full 360掳 rotation. 馃敼 Lead Vs. Pitch: In the typical standard case of one start thread, the lead equals the pitch (L=P). In multi-start threads, the lead equals the pitch times and the number of starts. (L=n*P) 馃敼 Lead Angle: The lead angle (蠁) measures the inclination of a screw helix from a plane that is perpendicular to the screw鈥檚 axis. In more simple words, it is the proportion between the screw鈥檚 lead and its diameter.
