JBO Thread Ring Gauge (GO) for Metric Fine threads is a precision tool used to verify external thread dimensions with speed and reliability. Designed for engineers, machinists, inspectors, and quality teams, it checks M118 x 1.5 right-hand threads to ensure parts meet exact standards.

• Go‑limit precision for metric fine threads: Quickly verify external threads against the M118 x 1.5 right‑hand specification, enabling fast pass/fail decisions and consistent quality checks.
• Hardened steel construction: With excellent wear resistance, the gauge maintains measurement accuracy through heavy daily use, delivering long service life in demanding workshop environments.
• Ergonomic, knurled design: The textured outer surface provides secure handling and quick orientation, reducing setup time and operator fatigue during inspections.

Using this GO gauge streamlines quality control by delivering repeatable checks in a single pass. Its durable build and precise geometry help you avoid rework, ensure thread compatibility across components, and support accurate documentation for audits and compliance. Whether in a high‑volume production line or a maintenance shop, this gauge helps you move parts through inspection faster while keeping tolerances tight and results reliable.
