The JBO Thread Ring Gauge (GO) – Metric Fine – Right Hand – 6g – M65 x 4 is a precision inspection tool used to verify external metric threads on fasteners, shafts, and threaded components. Designed for use in manufacturing, maintenance, and quality control, this GO gauge provides a clear go/no-go indication to confirm parts meet the exact diameter and pitch required for reliable mating and performance. It’s ideal for engineers, machinists, inspectors, and quality teams ensuring consistent thread compliance across processes.

Manufactured from hardened steel, the gauge delivers durable, wear-resistant performance in busy workshop environments. Its right-hand orientation and 6g tolerance class deliver reliable measurements over time, helping you maintain calibration and reduce re-checks. Sized for M65 x 4 metric fine threads, this gauge supports standardized inspections and fast, repeatable checks in high-volume settings.

• Precision GO gauge for metric fine threads: Quickly confirms external thread size M65 x 4 within 6g tolerance, enabling fast go/no-go decisions and tighter quality control.
• Hardened steel for durability: Withstands daily use in demanding environments, maintaining accuracy and extending service life to lower replacement and downtime costs.
• Ergonomic, right-hand design: Knurled, easy-grip surface and correct orientation support fast, accurate alignment with parts, reducing inspection time and user fatigue.

Using this gauge streamlines your QA workflow by delivering clear pass/fail results, helping you reduce rework, prevent mismatched assemblies, and support consistent outcomes across shifts. It’s a reliable choice for shops and labs that require repeatable, standards-based thread verification for external metric threads.
