The JBO Thread Ring Gauge (GO) - Metric Fine is a precision tool designed to quickly verify external metric threads. Built for right-hand M14 x 0.75 applications and 6g tolerance, it helps inspectors, machinists, and quality teams confirm that threaded parts meet specified standards.

Crafted from hardened steel for durability, this GO gauge resists wear in busy production lines and toolrooms, delivering consistent results over time. Its intuitive design makes it easy to identify properly conforming threads, supporting fast, confident quality checks wherever precision matters.

• Fast, one-step GO checks: Quickly verify that M14 x 0.75 external threads meet the 6g tolerance, speeding up quality inspections and reducing handling time.
• Durable hardened steel construction: Built to resist wear in busy workshops, preserving accuracy and extending tool life through demanding environments.
• User-friendly visual identification: The gauge geometry makes it straightforward to identify compliant threads at a glance, reducing inspection time and errors.

Using this GO gauge helps streamline QC workflows by providing a clear pass/fail reference for threaded parts. It supports faster decisions, minimizes downtime, and delivers reliable, repeatable measurements across shifts, helping you maintain consistent quality and traceable results.
