The JBO Thread Ring Gauge NoGo (Metric Fine, Left Hand, 6g, M70 x 2) is a precision inspection tool for checking external thread diameters. Designed for engineers, machinists, quality teams, and maintenance professionals, it provides fast, reliable conformance checks to ensure threaded parts fit and perform as intended.

• Premium hardened steel construction: Built to resist wear and maintain dimensional accuracy under daily use in busy workshops, reducing replacement costs and downtime.
• Metric Fine NoGo precision: Precisely machined to metric fine thread standards, enabling quick, unambiguous Go/NoGo checks of external threads to verify conformance.
• Left-hand thread compatibility: Specifically designed for M70 x 2 left-hand threads, allowing clear, reliable checks in assemblies that use left-handed fasteners.

In practice, this gauge speeds up quality inspections, minimizes rework, and helps maintain consistent thread quality across production runs. The rugged build and precise dimensions give technicians confidence that every thread will assemble correctly, helping your team meet tight tolerances and finish projects on time.
