The JBO Thread Ring Gauge (NoGo) is a precision inspection tool that helps you verify external metric thread diameters quickly and reliably. It is tailored for metric fine threads: M23 x 1, right-handed, 6h tolerance, making it ideal for quality control, machining, and assembly lines that require consistent pass/fail checks.

Manufactured from hardened steel, this gauge delivers exceptional durability and wear resistance, designed to hold its tight tolerances through daily use in demanding workshop environments.

• Precise NoGo Verification: Quickly confirms whether external threads meet the maximum size for M23 x 1 right-hand threads, enabling fast, confident pass/fail decisions with minimal rework.
• Durable Hardened Steel Construction: Built to resist wear and keep measurements stable over years of heavy use in busy shops and production floors.
• Standardized Metric Fine Size: Specifically sized for M23 x 1, right-hand, 6h tolerance, ensuring consistent results across components and simplifying gauge kit management.

With the JBO NoGo Ring Gauge you have a reliable, repeatable method for threading quality checks that helps speed inspections, reduce downtime, and uphold precise thread standards across your workflow.
