The JBO Thread Ring Gauge (NoGo) – Metric Coarse – Right Hand – 4h – M16 x 2 is a precision inspection tool designed to quickly verify external thread dimensions against standard limits. Ideal for engineers, machinists, quality teams, and workshop personnel, it helps ensure M16x2 coarse-threaded components meet exact specifications before they move to assembly.

The NoGo design provides a clear pass/fail indication for out-of-tolerance parts, enabling inspectors to identify non-conforming threads at a glance and keep production moving with fewer rechecks or guesswork.

• NoGo quick-pass/fail verification: Enables instant identification of non-conforming threads by comparing against the maximum limit, speeding up inspections and reducing guesswork in quality control.
• Durable hardened steel construction: Wear-resistant material stands up to daily use in busy workshops, helping maintain accurate measurements and extending tool life.
• Metric coarse, M16 x 2, right-hand, 4h compatibility: Precisely sized for common metric coarse threads with correct orientation and tolerance, ensuring reliable, repeatable checks that align with standard fasteners.

Incorporating this gauge into your quality workflow helps you validate fit and function quickly, reduce downtime, and maintain consistent results across batches. Its robust build and straightforward Go/NoGo assessment give you confidence in every measurement, whether you’re performing incoming inspection, in-process checks, or final quality control.
