The JBO Thread Plug Gauge (GO) - Metric Fine - Right Hand - 6H - M50 x 1 is a precision Go gauge designed to verify threaded holes in metal parts and assemblies. It helps engineers, machinists, inspectors, buyers, and hobbyists quickly confirm whether a hole is properly tapped to M50 x 1 with a metric fine pitch.

Made from hardened steel for lasting durability, this gauge resists wear in busy workshops and inspection rooms. Its GO designation provides a clear, reliable pass/fail test that supports consistent quality control across production runs.

• Precise metric GO gauge for M50 x 1 threads: Delivers consistent go/no-go results, speeds up inspections, and reduces guesswork to ensure mating parts fit correctly.
• Hardened steel construction for durability: Built to withstand daily use in demanding environments, resisting wear and maintaining accuracy over time.
• Right-hand orientation with 6H tolerance: Aligns with standard internal thread conventions and tolerances, delivering repeatable results with minimal rework.

With this gauge in your toolkit, you gain fast, confident inspections that keep production moving. Use it to validate hole sizes during assembly, ensure consistent thread quality across parts, and minimize downtime from faulty threads. The durable construction reduces replacement frequency and total lifecycle costs, while the precise M50 x 1 GO gauge helps you uphold tight tolerances and reliable performance in every job.
