JBO Thread Plug Gauge (GO) is a precision inspection tool designed to verify metric threaded holes quickly and reliably. This right-hand GO gauge targets fine metric threads, configured for M65 x 2 with a 6G tolerance, helping engineers, machinists, and quality teams confirm holes meet specification before assembly.

• Hardened steel construction: Built from high‑quality hardened steel to resist wear and maintain accurate GO sizing through repeated use in busy workshops.
• Precisely matched metric fine sizing: Machined to exact M65 x 2, 6G, right‑hand thread specifications to deliver reliable, repeatable go results in every inspection.
• User-friendly inspection design: Ergonomic knurled surface and straightforward go‑check engagement make it easy to identify properly threaded holes and move through QC steps fast.

Using the JBO GO gauge helps streamline quality control, shorten inspection times, and reduce the risk of assembling parts with out-of-spec threads. Its durable build supports daily use in demanding environments, delivering consistent results you can trust across lots and production runs.
