The JBO Thread Ring Gauge (NoGo) is a precision tool for confirming external metric fine threads. Specifically designed for left-hand threads (M14 x 1.25) and built to 6g tolerance, this NoGo gauge delivers quick, clear pass/fail checks in quality control, machining, and assembly environments. Crafted from hardened steel for durability, it stands up to daily use and maintains accurate readings over time.

• NoGo gauge for metric fine LH threads (M14 x 1.25) — 6g tolerance: Delivers fast pass/fail checks and consistent measurements, helping you quickly identify out-of-tolerance components and keep production moving.
• Left-hand thread testing: Specifically designed to test left-hand threaded components, ensuring accurate readings and preventing mix-ups in LH assemblies.
• Hardened steel construction: A durable, wear-resistant body that resists rust and wear, maintaining reading accuracy even in busy workshop environments.

Using this gauge helps you verify thread quality at a glance, speeding inspections, reducing rework, and preventing mismatched parts from entering assemblies. Its robust construction and precise NoGo testing deliver reliable results across batches, supporting consistent quality and improved workflow in manufacturing, repair, and maintenance applications.
