The JBO Thread Plug Gauge (NoGo) - Metric Fine is a precision inspection tool designed to validate metric fine threaded holes. Specifically sized for M88 x 2 right-hand threads with a 6H tolerance, it helps engineers, machinists, quality teams, and workshop technicians confirm holes meet exact size and pitch specifications.

Built for durability, this plug gauge is machined from hardened steel to resist wear in busy workshop environments. Its compact, knurled body offers a secure grip and easy insertion, while the NoGo reference provides a clear, decisive check of maximum thread size to support consistent, reliable measurements during setup and production.

• Go/NoGo style for fast hole acceptance checks: Quickly determine whether a hole meets metric fine thread size and tolerance, reducing guesswork and rework.
• Hardened steel construction for long life: Withstands daily use in demanding environments, maintaining accuracy and reducing replacement needs over time.
• Right-hand metric fine thread compatibility, M88 x 2, 6H: Ensures you’re inspecting the correct standard for common applications, delivering consistent results.

This gauge streamlines quality control by providing reliable, repeatable checks that confirm holes conform to the M88 x 2 fine-thread specification within the 6H tolerance. Using it in setup and production inspections helps speed up workflows, reduce downtime, and improve overall threading quality across manufacturing and maintenance tasks.
