The JBO Thread Ring Gauge (NoGo) — Metric Fine is a precision inspection tool designed to verify external thread diameters to exact metric standards. Suitable for engineers, inspectors, machinists, and technicians, it helps confirm that threaded components meet the M64 x 2 right-hand, 6e specification with confidence.

Crafted from hardened steel for durability, this gauge delivers long-lasting performance in demanding shop environments. Its robust construction resists wear and maintains dimensional accuracy, making it a reliable companion for routine quality checks and compliance verification.

• Go/No-Go quick checks: Quickly determine whether a thread diameter is within the accepted tolerance for M64 x 2 right-hand threads, helping identify non-conforming parts at a glance.
• Durable hardened steel construction: Built to withstand heavy use, resist wear, and provide stable, repeatable measurements over time in busy workshop environments.
• Precise metric fine threading (M64 x 2, right-hand, 6e): Delivers accurate, repeatable measurements aligned with standard metric thread profiles for reliable quality control and consistent results.

Using the JBO Thread Ring Gauge simplifies threaded component inspections, reduces rework, and speeds up quality workflows. Its combination of durability and precision gives you confidence that measurements are repeatable across inspections, supporting compliant assemblies and efficient maintenance. Rely on its straightforward use to quickly separate compliant parts from rejects and keep production moving smoothly.
