The JBO Thread Plug Gauge (NoGo) in Metric Fine is a precision tool designed to verify metric fine threaded holes. Built for machinists, inspectors, maintenance teams, and fabricators, it provides fast, reliable Go/NoGo checks for M72 x 1.5 threads.

• Go/NoGo verification: Quickly confirm if a threaded hole is within spec—the Go end should pass on correctly sized holes, while the NoGo end should not fit. This speeds inspections and reduces guesswork on the shop floor.
• Rugged hardened steel construction: Built to withstand daily use in busy workshops, resist wear, and maintain accuracy after repeated insertions and extractions.
• Right-hand, 6H, M72 x 1.5 specification: Specifically tuned for the metric fine thread form in this size, ensuring reliable measurements and easy integration into standard inspection routines.

In practice, this gauge speeds threaded-hole inspections, helping you reject out-of-tolerance parts before they move to assembly. With a durable hardened-steel build and precise sizing, you’ll enjoy consistent, confident measurements across batches and shift after shift, reducing rework and downtime in machine shops, production lines, and maintenance environments.
