A Thread Plug Gauge is a precision tool used to verify the internal threads of a hole or nut for accuracy and conformance to specific standards. It consists of two ends: the “Go” end, which should smoothly enter the threaded hole, and the “No-Go” end, which should not fit if the threads are within the required tolerance. Made from hardened steel, thread plug gauges are durable and designed for repeated use in quality control and inspection processes. They are widely used in industries like manufacturing, aerospace, and automotive to ensure that internal threads are properly sized for secure and accurate fastening. Their reliability makes them essential for maintaining product quality and preventing threading defects.
