JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M38 x 2

The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M38 x 2 is a precision inspection tool designed to verify external threads on fasteners, bushings, and machined components. It’s ideal for engineers, machinists, quality inspectors, and shop personnel who need reliable go/no-go checks to confirm threads meet exact size and pitch.

Crafted from hardened steel for durability in demanding environments, this gauge maintains consistent accuracy over time. Its metric fine pitch, right-hand orientation, and 4h class reference provide a dependable standard for checking M38 x 2 threads and ensuring parts fit as specified.

• Precise M38 x 2 metric fine sizing: Verifies the external thread diameter against the exact M38 x 2 standard, enabling quick pass/fail decisions for compliant parts.
• Hardened steel construction for long life: Built to withstand daily use in busy workshops, offering wear resistance and stable performance to reduce replacement costs.
• Clear go/no-go checks for fast inspection: Helps operators identify non-conforming threads at a glance, speeding up quality control and minimizing downtime.

Using the JBO NoGo gauge streamlines threading inspections, delivering repeatable results that support consistent assembly fits across production runs. The rugged construction and straightforward Go/No-Go workflow reduce training time and inspection effort, helping your team work more efficiently while maintaining tight threading standards.
