The JBO Thread Ring Gauge (GO) – Metric Fine is a precision go/no-go tool designed to verify external threads on threaded parts, fasteners, and fittings. With its metric fine configuration for M12 x 1 and right-hand threading, it helps inspectors and shop floor teams quickly confirm that components meet the exact size and pitch requirements.

• Accurate Go/No-Go verification: Quickly confirm external thread diameter and pitch against M12 x 1 metric fine, right-hand threads within the 4h tolerance, ensuring parts meet specification.
• Durable hardened steel construction: Built to resist wear in demanding environments, delivering long-lasting performance and reliable checks over time.
• User-friendly inspection tool: Clear, easy-to-read design supports fast, repeatable checks and straightforward identification of conforming components.

This gauge streamlines quality control by providing fast, reliable thread verification that supports consistent results across batches. Its rugged construction minimizes downtime and replacement costs, while its intuitive design makes it suitable for both seasoned technicians and new operators, helping you move parts through inspection with confidence.
