The JBO Thread Plug Gauge (NoGo) – Metric Fine, Right Hand, 6H, M50 x 1.5 is a precision inspection tool designed to verify threaded holes to metric fine standards. It’s ideal for machinists, quality teams, and shop floor inspectors who need fast, reliable go/no-go checks to ensure components meet tight thread tolerances.

• Accurate NoGo Limit for Metric Fine Threads: Delivers a clear pass/fail threshold for M50 x 1.5, 6H, right-hand threads, helping you quickly confirm hole size and reduce rework.
• Hardened Steel Construction for Durability: Built from hardened steel to resist wear and maintain dimensional accuracy through daily use in demanding environments.
• Ergonomic, Quick-Handling Design: Knurled body and compact form enable stable handling, fast insertion, and repeatable measurements across long inspection runs.

With this gauge in your toolkit, you gain confidence that every hole meets specification, speeding up your inspection workflow and reducing variance on the production line. The durable construction minimizes replacements, delivering reliable performance and long-term value in quality control.
