The JBO Thread Ring Gauge (NoGo) – Metric Coarse, Right Hand, 6h, M6 x 1 – is a purpose-built inspection tool for external threads. It helps quality teams, machinists, and inspectors quickly verify that M6 x 1 right-hand threads meet the NoGo limits and conform to metric coarse thread standards, ensuring consistent fit and reliable performance in assemblies.

Crafted from hardened steel for durability, the gauge resists wear in busy workshops and maintains precise dimensions over time. A knurled outer edge provides a secure grip for easy handling, while the compact ring design enables reliable use in tight spaces during routine QC checks.

• Accurate Go/NoGo verification for metric coarse threads: Quickly confirms whether an external M6 x 1 right-hand thread falls within the NoGo limit, reducing guesswork and speeding inspections to ensure parts meet spec.
• Durable hardened steel construction: Built to withstand daily use in demanding environments, maintaining dimensional integrity and delivering long service life.
• Intuitive, fast identification of non-conforming parts: Clear, easy-to-read results help you spot out-of-spec threads at a glance, boosting inspection throughput and confidence in each check.

Using the JBO Thread Ring Gauge simplifies quality control workflows, saves inspection time, and helps ensure reliable, repeatable results for metric coarse thread fits. It supports consistent assembly performance by confirming M6 x 1 right-hand threads meet the required 6h tolerance and NoGo criteria, giving teams confidence in every part they validate.
