At Harshman Gauges & Engineering Company, we specialize in supplying high-precision GO and No-Go Thread Ring Gauges designed to inspect and verify the accuracy of external threads. Our gauges are trusted for their durability, consistency, and superior measurement accuracy, making them essential tools in quality control and manufacturing processes.
GO and No-Go Thread Ring Gauges are used to check the correctness of external threads on screws, bolts, and threaded shafts. The GO ring gauge ensures that the part fits within the minimum tolerance, while the No-Go ring gauge ensures it does not exceed the maximum limit—providing a simple yet effective way to maintain quality standards.
