The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 4h, M22 x 0.75, is a precision tool designed to verify external thread diameters with confidence. Built for engineers, machinists, inspectors, and workshop teams, it helps confirm components meet the required 4h tolerance quickly and reliably.

• Precise GO gauge for metric fine threads: delivers quick, pass/fail verification against the M22 x 0.75 4h external thread spec, reducing measurement guesswork.
• Hardened steel construction: stands up to daily use, resisting wear and maintaining accurate tolerances over time for reliable inspections.
• User-friendly inspection tool: intuitive design lets operators identify properly conforming parts at a glance, cutting inspection time and downtime.

Using this gauge helps you streamline quality control, reduce rework, and deliver consistently threaded components that meet specification, improving overall production reliability and confidence in every part.
