Smooth plug gauge is a precision instrument for measuring the inner dimensions of a workpiece. It is produced in two types: the maximum limit dimension version and the minimum limit dimension version; the minimum end is the through end, and the maximum end is the stop end. During measurement, the through-end plug gauge should pass through the small diameter, while the stop-end plug gauge should not pass through the small diameter.
