The JBO Thread Ring Gauge (GO) – Metric Coarse, Right Hand, 6g, M11 x 1.5 is a precision inspection tool designed to verify external thread engagement quickly and reliably. Used by machinists, quality inspectors, and assembly technicians, it provides a clear go/no-go reference to ensure parts meet the M11 x 1.5 coarse-thread standard.

Constructed from hardened steel for exceptional wear resistance, this GO gauge delivers lasting accuracy in busy workshops. Its simple, intuitive design—with a knurled outer edge for easy handling—lets operators perform fast, repeatable checks, helping to maintain consistent thread quality across production runs.

• Precise GO measurement for M11 x 1.5 coarse threads: Machined to exact external thread dimensions so you can quickly verify correct fit and reliable engagement during inspections.
• Hardened steel construction: Built to resist wear and preserve tolerance, delivering durable performance even in high-use QC environments.
• Right-hand design with easy-grip knurling: Specifically tailored for right-hand threads and easy handling in tight spaces, speeding up setup and reducing inspection time.

By providing a clear, trustworthy reference for thread size and pitch, this gauge helps streamline quality control, minimize rework, and ensure consistent results in metric coarse threaded assemblies.
