Thread Gauge: Metric

Acceptance criteria for components

The GO gauge when screwed by hand without using excessive force, should enter and pass the whole length of the workpiece thread.
The NOT GO gauge when screwed by hand without being forced, should not enter the component by more than three complete turns.

Thread Gauge: Multi Start

Multi-start threads

Multi start threads are used where quick axial travel is desired with less rotation. These are also used for threads which cannot have coarse pitches due to metallurgical constraints. In comparison to single start threads, multi start threads can accept higher axial thrusts for restricted angles of rotation, the efficiency is high, the tendency to locking is reduced. Multi start threads are commonly used in power transmitting screws, valve spindles.
