The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision inspection tool designed to verify metric fine threaded holes with consistent, reliable results. It's ideal for engineers, machinists, inspectors, and workshop teams who need fast, clear pass/fail feedback.

Built for demanding environments, this Right Hand NoGo gauge targets M72 x 6 metric fine threads with a 6H tolerance. Crafted from hardened steel, it delivers durable, wear-resistant performance that stands up to daily use in busy shops.

• Metric-fine thread verification: Precisely sized for M72 x 6 threads with 6H tolerance to quickly confirm holes meet spec, reducing guesswork and rework.
• NoGo condition for reliable tolerances: The NoGo design ensures holes are not oversized beyond tolerance, helping catch drift in production before assemblies fail.
• Durable, secure-handling construction: Hardened steel body with a knurled grip provides long life and confident handling in busy environments.

Using the JBO Thread Plug Gauge (NoGo) helps you speed up quality checks, improve measurement consistency, and reduce downtime by quickly confirming that M72 x 6 threaded holes conform to the 6H tolerance. With hardened steel construction, you can rely on repeatable results across production runs, assemblies, and inspections—giving your team confidence to move forward with each part.
