The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6g, M52 x 1.5 – is a precision tool designed for fast, reliable verification of external threads. Suited for engineers, machinists, quality inspectors, and shop floor teams, it helps you confirm that components with M52 x 1.5 right-hand threads meet the exact size and tolerances required, improving first-pass acceptance and reducing rework.

• Precise Go gauge for external threads: Quickly verify that the external thread diameter and pitch meet the M52 x 1.5 right-hand, 6g specification, enabling fast pass/fail decisions during inspection.
• Hardened steel construction for durable reliability: Crafted from hardened steel to resist wear in busy workshops, delivering long tool life and consistent measurements even after heavy use.
• Ergonomic, easy-to-use design: Knurled outer surface and a simple, intuitive GO reading allow for secure handling and quick checks, reducing setup time and operator fatigue.

By providing a quick, definitive indication of conformance, this gauge helps you speed up QA checks, minimize mis-sized parts, and keep production flowing. Its rugged construction means fewer tool changes and replacements over time, while its precise GO reading supports consistent results across operators and shifts, making it a dependable addition to any precision machining, assembly, or inspection workflow.
