The JBO Thread Ring Gauge (NoGo) - Metric Coarse - Left Hand - 6g - M11 x 1.5 is a precision inspection tool designed to verify external thread diameters on fasteners, fittings, and machined parts. Specifically configured for left-hand metric coarse threads, it supports quick pass/fail decisions against the M11 x 1.5 size with a 6g tolerance, helping you maintain consistent quality across assemblies.

Crafted from durable hardened steel, this NoGo gauge delivers long-lasting wear resistance in busy workshop environments. Its user-friendly design enables easy identification of non-conforming components, simplifying quality checks and speeding up routine inspections without sacrificing accuracy.

• Precise NoGo verification: Quickly determine if external threads exceed the specified size, enabling fast acceptance or rejection and reducing inspection time.
• Durable hardened steel construction: Built to resist wear in demanding settings, maintaining accuracy and extending tool life through busy production runs.
• Left-Hand metric coarse compatibility (M11 x 1.5, 6g): Designed for the correct fitment check of left-hand threaded parts, minimizing confusion and ensuring reliable, consistent results.

Incorporating the JBO NoGo Ring Gauge into your inspection workflow helps ensure metric coarse threaded connections meet standard requirements, improving assembly reliability and reducing downtime from incorrect fittings. Its robust build and precise dimensions give you confidence in pass/fail decisions, supporting quality control and precise engineering outcomes across projects.
