The JBO Thread Ring Gauge (NoGo) — Metric Fine, Right Hand, 6e, M23 x 1 — is a precision inspection tool for measuring external thread diameters. Designed for engineers, inspectors, machinists, and quality teams, it helps you quickly verify that threaded components meet the exact size and tolerance required by your drawings and standards.

Constructed from hardened steel for durability, this gauge resists wear in busy shops and demanding environments. The NoGo design provides a clear, immediate indication of non-conforming threads, supporting reliable quality control and efficient precision engineering.

• NoGo quick-pass/fail checks: The NoGo design enables rapid verification that external threads do not exceed the maximum permitted diameter, speeding inspections and reducing guesswork.
• Metric Fine compatibility (M23 x 1, 6e, Right Hand): Precisely matches the intended fine-thread class and hand direction, ensuring accurate checks and straightforward cross-reference with specifications.
• Hardened steel durability: Built to withstand heavy use, delivering long service life and consistently reliable measurements in challenging environments.

With this gauge in your toolkit, you can streamline threaded-component inspection, cut downtime due to uncertain measurements, and improve overall fit quality across assemblies. It supports repeatable, inspector-friendly checks that help you meet standards, reduce rework, and keep production moving smoothly.
