The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6g, M2.5 x 0.2 is a precision inspection tool designed to verify external thread diameters on metric fasteners and threaded components. Built for engineers, machinists, quality inspectors, and workshop technicians, it provides a simple, reliable pass/fail check that helps you confirm parts meet exact specifications before assembly or shipment.

Made from hardened steel for excellent wear resistance, this NoGo ring gauge stays accurate under demanding use. The clear, right-hand metric design makes it easy to recognize non-conforming parts during routine QC, reducing guesswork and rework while speeding up inspections in production lines or job sites.

• NoGo design for quick pass/fail checks: Enables fast identification of external threads that are out of tolerance, helping you decide immediately whether a part can be used or must be rejected.
• Metric fine compatibility (M2.5 x 0.2, 6g, Right Hand): Precisely matched to the M2.5 x 0.2 fine pitch and relevant class, ensuring consistent measurements across parts and assemblies.
• Hardened steel construction for durability: Built to withstand everyday workshop use, resisting wear and maintaining accuracy over time even in busy environments.

With the JBO NoGo Ring Gauge, you gain a dependable tool that speeds up quality control, reduces downtime due to uncertain measurements, and helps you uphold tightening and fitting standards across your projects. This gauge provides consistent results, supports repeatable inspections, and gives you confidence that every threaded part either fits or is set aside for rework, ensuring reliable performance in your assemblies.
