The JBO Thread Ring Gauge (GO) – Metric Fine is a precision tool for verifying external metric threads, including M30 x 2 right-hand threads. It serves quality control teams, machinists, engineers, and maintenance professionals who need fast, reliable GO checks on threaded components.

Crafted from hardened steel, this ring gauge resists wear and maintains accuracy through frequent use in busy workshops. Its GO design makes it easy to identify properly conforming threads at a glance, helping reduce rework and speed up inspections.

• Hardened steel construction: Built to resist wear and maintain dimensional accuracy in demanding environments, delivering long service life.
• Metric fine GO gauge for M30 x 2: Precisely sized to verify external threads, enabling fast, reliable pass/fail decisions during inspection.
• Right-hand, 6h configuration: Aligns with standard right-hand threads and provides a consistent reference for quality checks across parts.

Using the JBO Thread Ring Gauge (GO) – Metric Fine streamlines thread inspection, reduces guesswork, and supports consistent results across production runs. Its durable construction and precise geometry help you improve throughput, catch non-conforming components early, and maintain confidence in your threaded assemblies.
