JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M55 x 2

The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed for external threads. It’s ideal for engineers, machinists, quality control teams, and workshop professionals who need fast, reliable checks of threaded components against metric fine standards. Specifically sized for M55 x 2 threads, this gauge helps you quickly determine if a part meets the required tolerance.

Built for durability, the gauge features a hardened steel body that resists wear and maintains accuracy through many inspection cycles. The metric fine NoGo design is tailored to verify M55 x 2 threads, helping you reliably identify parts that fail to meet specification. With its right-hand orientation, it fits naturally into standard inspection workflows, making go/no-go checks straightforward and efficient.

• Durable hardened steel construction: Withstanding daily use in demanding workshop environments, it maintains precise measurements and long-lasting performance.
• Metric Fine NoGo design for M55 x 2 threads: Precisely sized to verify the specific thread, enabling quick, repeatable pass/fail decisions during inspection.
• Easy-to-use go/no-go interface: Clear, straightforward checks reduce setup time and help identify non-conforming components at a glance.

Used in incoming, in-process, and final inspections, this gauge streamlines quality control by delivering consistent results with minimal interpretation. Its robust construction and exact dimensions support reliable performance across assemblies and production runs, giving you confidence in every measurement and helping to keep your workflow efficient and compliant.
