The JBO Thread Ring Gauge (GO) – Metric Fine is a precision Go gauge used to verify external thread diameters on metric threads. It helps engineers, machinists, and quality teams quickly confirm that components with M132 x 1.5 threads meet the required specification.

Crafted from hardened steel, this gauge delivers durable, wear‑resistant performance in demanding workshop environments. Its straightforward design makes it easy to identify properly conforming threads, supporting reliable quality control and precision assembly.

• Precise metric fine-thread verification: Quickly verify external thread diameters to confirm M132 x 1.5 conformance with repeatable results.
• Durable hardened steel construction: Built to resist wear in busy shops, ensuring long service life and consistent performance across jobs.
• User-friendly, fast part conformance identification: Intuitive shape and GO gauge principles help operators quickly determine whether a threaded component passes inspection, reducing downtime.

By providing a clear, reliable reference for external thread size, the JBO Thread Ring Gauge streamlines your inspection workflow. It helps reduce rework and guesswork, speeds up quality checks, and supports consistent, compliant assemblies across production runs.
