I am making a new led screw due to the broken led screw of a machine in America.
led screw out diameter= 50 mm.
pitch =8 mm.
What is thread pitch?
Thread pitch, or pitch, in short, is the distance between the same point on two adjacent threads. Thread pitch can be the length between two crests or two roots of a thread.
As long as we measure two identical points on two threads next to each other, we are measuring the thread pitch. Thread pitch also tells us how wide a threaded fastener's thread is.
