JBO Thread Plug Gauge (GO) – Metric Fine – Right Hand – 6H – M55 x 2 is a precision inspection tool used to verify threaded holes to the M55 x 2 fine-pitch standard. Designed for engineers, machinists, inspectors, and shop-floor teams, it provides a reliable go gauge that confirms correct thread size and tolerance, enabling fast, confident QA checks in busy production environments.

• Quick, go/no-go verification: Enables fast checks of M55 x 2 threaded holes, reducing inspection time and helping you identify non-conforming parts early in the process.
• Durable hardened steel construction: Built to endure daily use, with wear-resistant surfaces and a knurled grip for secure handling in challenging workshop conditions.
• Metric fine, right-hand 6H tolerance: Precisely formed to the 6H class for consistent results across parts and operators, supporting reliable quality control and traceability.

Using this gauge, you gain a dependable, fast method to confirm threaded hole acceptance, improving first-pass yield and overall workflow. The robust build resists wear, so replacements are less frequent, while the clear GO indication simplifies decision-making on the shop floor. Integrate it into your QA routine for repeatable, accurate results that help you meet demanding tolerances with confidence.
