The JBO Thread Plug Gauge (NoGo) is a precision inspection tool designed for metric fine threaded holes. Specifically built for right-handed M95 x 4 threads and 6H internal tolerance, it helps technicians and manufacturers confirm hole size quickly and reliably.

Crafted from hardened steel with a textured knurled body, this NoGo gauge withstands daily use in busy workshops while maintaining accurate measurements. Its design supports straightforward go/no-go checks, ensuring threaded holes meet the required specification before assembly or finishing.

• Precise metric fine NoGo verification: Enables quick, repeatable go/no-go checks for M95 x 4 holes at 6H tolerance, reducing guesswork and the need for rework.
• Hardened steel construction: Built to resist wear and maintain accuracy in demanding environments, delivering long service life.
• Ergonomic knurled body: Provides a secure grip and easy handling, speeding inspections even in tight spaces.

This gauge helps you streamline quality checks, minimize downtime due to out-of-tolerance holes, and ensure consistent results across production runs. Its durable build and precise compatibility with metric fine threads give you reliable, repeatable measurements you can trust day after day.
