The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M122 x 2 is a precision tool designed to verify external thread diameters with speed and confidence. It is ideal for inspectors, machinists, engineers, and quality-control teams who need reliable go/no-go checks to confirm parts meet exact thread size.

Crafted from hardened steel, this GO gauge delivers durability and long life in demanding shop environments. Its metric-fine specification (M122 x 2) is focused on accurate, repeatable measurements, making it a dependable choice for standard-thread verification and quality control workflows.

• Precise GO sizing for metric fine threads: Quickly verify external thread diameters to confirm parts conform to M122 x 2 specifications, speeding up inspection and reducing rework.
• Durable hardened steel construction: Built to resist wear and maintain dimensional accuracy in demanding environments, delivering long service life across thousands of measurements.
• Easy-to-use, quick pass/fail identification: The ring gauge design enables fast, unambiguous checks so operators can sort conforming parts at a glance and keep production moving.

The GO gauge helps you trust every measurement, streamline quality checks, and reduce downtime by delivering clear, repeatable results for external metric fine threads. With reliable performance from hardened steel construction, it supports consistent assembly, maintenance, and repair tasks across the workshop.
