The JBO Thread Plug Gauge (NoGo) is a precision tool designed for metric fine internal threads. Ideal for engineers, machinists, inspectors, and maintenance personnel, it provides quick, reliable go/no-go checks to verify holes meet the M85 x 6 specification within the 6H tolerance. Built for practical use in everyday workflows, this gauge helps you confirm threaded holes are within spec without guesswork.

• Go/No-Go verification for metric fine threads: Quickly confirm M85 x 6, 6H internal threads with clear pass/fail feedback, helping you reject out-of-tolerance holes before they move to the next production stage.
• Hardened steel construction for durability: Designed for frequent use in demanding environments, it resists wear and maintains accurate measurements over time.
• Ergonomic right-hand design with knurled grip: Secure, comfortable handling that supports consistent, repeatable measurements even in tight or awkward setups.

Using this gauge streamlines quality checks, speeds up acceptance decisions, and provides confidence that threaded holes conform to exact metric fine standards. The NoGo design delivers decisive, easy-to-interpret results, helping you reduce scrap, rework, and downtime while delivering reliable, repeatable inspections for M85 x 6 threads in 6H tolerance.
