The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric threads. Specifically configured for left-hand, fine-pitch threads (M72 x 2) with 6g tolerance, it helps machinists, inspectors, and quality teams quickly confirm parts meet spec without guesswork.

• Durable hardened steel construction: Built to resist wear in busy workshops, ensuring long life and sustained accuracy through countless inspections.
• Metric fine compatibility with M72 x 2 and 6g tolerance: Precisely sized for metric fine-thread standards, enabling reliable NoGo checks and consistent quality control outcomes.
• Left-hand thread design with secure grip: Specifically tailored for left-hand threads, featuring a knurled edge for easy handling and fast, error-free measurements in tight spaces.

With this gauge, inspections become faster and more dependable. It helps you quickly flag out-of-spec threads, reduce rework, and maintain consistent thread quality across production runs, giving your team confidence in every assembly and procurement decision.
