The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6g, M45 x 2 is a precision tool designed to inspect external threads on fasteners, fittings, and machined parts. Built for metric fine thread applications and right-hand threads, this GO gauge helps verify that components meet the required diameter and thread form during quality checks.

Made from hardened steel, it offers excellent durability and wear resistance in demanding shop environments. Its straightforward GO design makes it easy to identify properly conformed threaded components, speeding up inspection and supporting consistent, reliable results in quality control and precision engineering.

• GO Gauge for Metric Fine Threads: Quickly verify external thread diameters against metric fine standards, including the M45 x 2 specification, to confirm parts meet required thread form during inspection.
• Hardened Steel Construction: Designed for long life in busy workshops, this gauge resists wear and maintains measurement accuracy through repeated use.
• User‑Friendly Go Gauge Design: Simple, intuitive checks help you rapidly distinguish conforming parts from outliers, reducing inspection time and improving workflow consistency.

This GO thread ring gauge helps you streamline your quality checks, minimize rework, and document compliant parts with confidence. By delivering repeatable, accurate results quickly, it supports faster production cycles, better traceability, and higher overall quality in assemblies that rely on metric fine threaded connections.
