Description

This JBO NoGo thread ring gauge provides a dependable way to verify the external threads on left-hand M13 x 0.5 metric fine components. It quickly shows whether a threaded part exceeds the maximum allowable diameter, helping inspectors and machinists confirm compliance with 6g tolerance standards before parts move to assembly or shipment.

Accurate NoGo verification: Instantly identifies oversize threads so only correctly sized parts pass inspection, reducing the risk of assembly issues later.
Hardened steel construction: Resists wear during repeated use in busy workshops, maintaining consistent accuracy over time.
Clear visual marking: The red dot distinguishes this NoGo gauge from Go gauges at a glance, preventing mix-ups during daily quality checks.

Using this gauge as part of your inspection routine helps maintain tight control over thread quality, shortens verification time, and supports consistent output in precision engineering and manufacturing environments.
