The JBO Thread Ring Gauge (NoGo) – Metric Fine, Left Hand, 6g, M17 x 1.5, is a precision tool designed to verify external thread diameters quickly and reliably. Built for inspectors, machinists, and quality teams, it helps ensure components with metric fine threads meet the required size limits and specifications.

• Precise NoGo check for M17 x 1.5 left-hand threads: Quickly verify the external thread diameter against the maximum limit to identify out-of-tolerance components and prevent improper assemblies.
• Hardened steel construction for durability: Harnesses rugged, wear-resistant material to maintain accuracy through frequent use in busy workshops and production environments.
• Metric Fine tolerance with left-hand orientation: Specifically tailored for left-hand, metric fine threads (6g), delivering reliable results and reducing setup errors during inspections.

Used in quality control, this gauge streamlines inspections, helps you catch non-conforming parts early, and supports consistent thread quality across production batches. Its sturdy construction and precise dimensions give you confidence that your threaded components will fit correctly and meet your standards, even in demanding work settings.
