The JBO Thread Ring Gauge (NoGo) - Metric Fine, Right Hand, 6h, M12 x 0.75 is a precision inspection tool designed to verify external thread diameters on fasteners, fittings, and machined components. Built for engineers, quality inspectors, machinists, and shop teams, it helps ensure parts meet exact metric fine-thread specifications before assembly or production.

Threaded to exacting standards, this NoGo gauge features a hardened steel body for long life in busy environments. Its knurled outer edge provides a secure grip, while the red datum marker aids quick orientation during setup. The Right Hand orientation and 6h tolerance class deliver a clear pass/fail result, making it easy to spot non-conforming threads at a glance.
