The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external threads to the metric coarse standard. Specifically configured for M14 x 2 right‑hand threads, this NoGo gauge helps inspectors confirm that components do not exceed the maximum diameter allowed for proper mating.

Manufactured from hardened steel, the gauge delivers durability and wear resistance for daily use in demanding environments. Its rugged construction supports long service life, making it a reliable choice for quality control, machining, and assembly workflows.

• Accurate NoGo check for M14 x 2 coarse threads: Quickly confirms the maximum permissible external diameter for standard coarse threads, helping prevent oversized parts from passing inspection and ensuring proper mating with components.
• Durable hardened steel construction: Built to withstand daily use in busy workshops and production lines, delivering long life and reliable performance even in demanding environments.
• Clear, fast pass/fail inspection: Designed for straightforward use, providing immediate, unambiguous results that support efficient quality control and reduce rework or delays.

Using this NoGo gauge helps ensure metric coarse threaded connections meet defined standards, improving fitment consistency across assemblies. It speeds inspections, reduces rework, and gives teams confidence that every part will perform as intended in the final product.
