The JBO Thread Ring Gauge (NoGo) is a precision tool for validating external metric threads. It’s specifically configured for right-handed, metric-fine threads—M85 x 1.5 with a 6h tolerance—making it ideal for inspectors, machinists, and quality teams who need quick, reliable size checks.

Made from hardened steel and machined to tight tolerances, this NoGo gauge resists wear in busy shops and maintains accuracy across repeated use, ensuring durable, long-lasting performance.

• Metric fine thread verification (M85 x 1.5, Right Hand, 6h): Designed for precise external thread diameter checks to ensure components meet spec and fit correctly within assemblies.
• Hardened steel construction for durability: Built to withstand daily inspection routines, resisting wear and maintaining tight tolerances over time.
• Intuitive, quick pass/fail assessment: Enables fast identification of non-conforming parts, reducing inspection time and downstream rework in production workflows.

In practice, the JBO Ring Gauge helps you speed up quality control, reduce rework, and improve overall machining and assembly outcomes. Its precise dimensions translate to repeatable results across shifts, while the robust build minimizes replacement costs and downtime. Use it to verify every threaded part meets your standards before products move to the next stage of manufacturing or assembly.
