The JBO NoGo Ring Gauge for Metric Fine threads is a precision tool designed to verify external threads on components with M55 x 3 right-hand threads. Specifically built for quality control, machining, and assembly environments, this gauge helps you confirm that parts meet exact size and pitch requirements before they move to production or shipment. With a 6g tolerance class and a hardened steel construction, it delivers reliable, long-lasting performance in demanding workshop conditions.

• Precisely machined metric fine NoGo for M55 x 3: Ensures external threads are within the NoGo limit for accurate pass/fail checks, helping catch undersize or out-of-tolerance parts at a glance.
• Hardened steel construction: Built to resist wear and maintain dimensional stability, providing durable performance in busy inspection environments.
• Easy, repeatable inspections: Right-hand orientation and straightforward go/no-go check support quick setup and consistent results, reducing inspection time and training requirements.

Using the JBO NoGo Ring Gauge helps streamline quality control by quickly identifying non-conforming threaded components, supporting reliable mating in assemblies and consistent results across batches. It’s a practical addition to any precision-focused workshop, QA bench, or manufacturing line that requires dependable thread verification with minimal downtime.
