The JBO Thread Plug Gauge (GO) for Metric Fine threads is a precision internal-thread inspection tool designed to verify that threaded holes meet exact standards. With Right Hand orientation, a 6H tolerance, and the M80 x 3 size, it provides a reliable go gauge to confirm proper hole size and ensure consistent assembly across parts.

Manufactured from hardened steel and ground to tight tolerances, this GO gauge delivers excellent wear resistance and long service life in demanding workshops. Its robust construction and clear, repeatable measurements help quality teams maintain accurate records and reduce guesswork during inspections.

• Durable hardened steel construction: Built to withstand daily insertions and removals, maintaining precision and extending tool life in busy QC benches.
• Metric fine-thread compatibility (M80 x 3, 6H): Calibrated to standard metric fine internal threads, ensuring consistent go checks and reliable pass/fail decisions.
• Ergonomic, quick-to-use GO gauge: Knurled grip and straightforward alignment enable fast, confident inspections even in tight spaces.

Using the JBO GO plug gauge helps streamline quality control, reduce downtime, and improve first-time-right assembly. Its durable construction and precise sizing mean you can trust measurement results, support traceability in your quality records, and keep your production lines moving with fewer reworks.
