The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M30 x 2 is a precision inspection tool designed to verify external thread diameters. It’s ideal for manufacturers, machinists, quality teams, and maintenance professionals who need fast, reliable checks to confirm parts meet exact standards and specifications.

• Accurate metric fine threading (M30 x 2, 4h): ensures external threads match the exact diameter and pitch required for proper fit and reliable performance in assemblies.
• NoGo verification for quick pass/fail decisions: helps you identify non-conforming parts at a glance, reducing inspection time and preventing oversized components from moving forward in production.
• Durable hardened steel construction: built to withstand daily use in demanding environments while maintaining long-term accuracy and wear resistance.

Using the gauge streamlines quality control by providing clear, repeatable checks that support consistent results across batches. With its rugged build and precise tolerances, you can trust it to improve workflow, minimize downtime, and uphold tight threading standards in your operations.
