The JBO Thread Ring Gauge (GO) — Metric Fine, Right Hand, M2.5 x 0.2 — is a precision tool for verifying external thread diameters to exact metric standards. Designed for machinists, quality inspectors, engineers, buyers, and even serious hobbyists, it streamlines inspection by providing a clear go/no-go reference to confirm that threaded components fit as intended.

Built with durability in mind, the gauge uses hardened steel construction to resist wear and maintain accuracy through years of use in demanding workshop environments.

• Exact metric fine GO gauge for M2.5 x 0.2 threads: Quickly verify external thread diameters against the precise M2.5 x 0.2 standard, enabling fast pass/fail decisions during inspection and assembly.
• Hardened steel construction for long life: Durable, wear-resistant material stands up to daily use in demanding environments, preserving accuracy over time.
• Ergonomic, easy-to-use design: Knurled outer surface and simple seating ensure secure handling and consistent results, even during busy shifts.

By providing a quick, reliable measurement reference for external threads, this GO gauge helps streamline quality control, reduce inspection time, and improve overall fit accuracy across assemblies. Its robust construction minimizes downtime and replacement costs, while its clear pass/fail indication supports consistent results in production, QA documentation, and supplier acceptance testing. Whether you’re in a high-volume shop or a small workshop, the JBO Thread Ring Gauge (GO) helps you trust every threaded connection you produce or verify.
