The JBO Thread Ring Gauge (NoGo) – Metric Fine is a precision inspection tool designed to verify external thread diameters with tight tolerances. It’s built for engineers, machinists, quality teams, and workshop professionals who need fast, reliable checks to confirm parts meet required standards.

Specifically configured for metric fine threads at M25 x 2 in left-hand orientation, this gauge combines precise dimensions with durable construction. Made from hardened steel, it stands up to daily use in busy workshops, delivering consistent performance and accurate results during routine inspections.

• Precisely calibrated for metric fine threads: The gauge targets external thread diameters for M25 x 2 left-hand threads, enabling quick, reliable pass/fail decisions during inspection.
• Hardened steel construction for durability: Built to resist wear, ensuring long tool life and dependable performance even in demanding environments.
• User-friendly NoGo inspection: Clear non-conforming indications streamline quality control, helping you identify out-of-spec parts fast and reduce rework.

Integrate the JBO Thread Ring Gauge into your QC workflow to speed up inspections, improve first-pass yields, and maintain consistent thread quality across batches. By detecting out-of-tolerance parts early, you reduce downtime and prevent mismatches in assemblies, delivering reliable results and peace of mind in your manufacturing or maintenance processes.
