The JBO Thread Ring Gauge (NoGo) for Metric Fine threads is a precision inspection tool designed to verify external threads on components with accuracy and speed. Ideal for machinists, quality control inspectors, technicians, and engineers, this NoGo gauge helps you quickly confirm that parts meet the M23 x 0.75 metric fine specification and fail fast when out of tolerance.

Constructed from hardened steel for outstanding wear resistance, the gauge offers long-lasting durability in busy workshops. The NoGo configuration and right-hand orientation simplify setup and ensure consistent, repeatable results across multiple inspections and production runs.

• Precision NoGo verification for M23 x 0.75: Quickly confirms external thread diameter against the defined NoGo limit, helping you isolate non-conforming parts in minutes.
• Durable hardened steel construction: Built to endure daily use in demanding environments, delivering reliably long service life with minimal wear.
• Right-hand orientation for easy setup: Aligns with standard machining setups, enabling fast, intuitive checks and consistent results across parts.

By using this gauge, you streamline threading inspections, reduce downtime, and minimize scrap by clearly signaling when a part falls outside the acceptable size range. Its robust build and precise dimensions give you confidence that checks are repeatable, enabling tighter quality control and smoother production workflows.
