For best quality practice, go and no-go thread gauges should be used together. Go thread gauges are used for gauging the effective diameter of the thread. If the go thread gauge fits the thread, the work piece should be accepted. The no-go thread gauge is an oversized gauge also used for gauging the effective diameter of the thread. If the no-go thread gauge fits the thread, the work piece should be rejected.
