JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M3.5 x 0.25

The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric fine threads. Specifically tuned for right-hand M3.5 x 0.25 threads and 6g tolerance, this gauge helps ensure parts meet the exact thread dimensions required for reliable assembly. It’s well suited for engineers, machinists, quality inspectors, and workshop teams needing fast, conclusive go/no-go checks.

Manufactured from hardened steel, the gauge resists wear in busy shops and inspection environments, delivering long service life and consistent performance. The clearly defined NoGo profile makes it easy to spot out-of-spec parts, supporting reliable quality control with minimal training.

• Accurate NoGo verification for metric fine threads: Quickly confirm external M3.5 x 0.25 threads are within tolerance; a single check reveals out-of-spec parts and reduces rework.
• Hardened steel construction for durability: Built to withstand daily use, resisting wear and maintaining accuracy over time in busy workshops.
• Easy non-conforming identification: The NoGo profile provides a clear, quick indication of non-conforming threads, speeding inspection decisions and reducing guesswork.

With the JBO NoGo gauge, you can streamline quality control, speed up assembly-ready checks, and minimize rework. Its precise dimensions and robust build translate to reliable, repeatable results across shifts, helping teams maintain consistent quality and achieve better overall throughput when working with M3.5 x 0.25 threads.
