The JBO Thread Ring Gauge (NoGo) is a precision tool for fast, reliable verification of external metric threads. Designed for metric fine threads such as M14 x 0.5, with right-hand threading and a 4h tolerance, it helps inspectors, machinists, and quality teams quickly confirm parts meet specification.

Made from hardened steel, this ring gauge resists wear and maintains accuracy in demanding workshops. The NoGo design makes non-conforming threads obvious at a glance, supporting consistent, repeatable checks across teams.

• Precise NoGo verification for metric fine threads: Quickly confirm M14 x 0.5 external threads meet diameter and pitch requirements, enabling fast pass/fail decisions and reducing rework.
• Durable hardened steel construction: Built to withstand daily workshop use, resisting wear and deformation so accuracy stays consistent over time.
• Right-hand orientation with 4h tolerance: Aligns with standard production threading, ensuring reliable, repeatable checks that fit seamlessly into existing inspection protocols.

Using the JBO Thread Ring Gauge (NoGo) streamlines quality checks, minimizes downtime, and reinforces consistent thread conformance across your production and maintenance workflows. The combination of precise sizing and rugged durability delivers dependable results that engineers, buyers, and technicians can trust for repeatable inspections and reduced scrap.
