What is a Lead of a Thread? 

🔹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° rotation.
🔹 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)
🔹 Lead Angle: The lead angle (φ) measures the inclination of a screw helix from a plane that is perpendicular to the screw’s axis. In more simple words, it is the proportion between the screw’s lead and its diameter.
