The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 4h, M65 x 2 is a precision inspection tool designed to verify external thread diameters on fasteners and threaded components. It helps quality teams, engineers, machinists, and shop technicians quickly determine if a part is within the required tolerance, supporting reliable assembly and consistent quality.

Designed for professional use across industries, this gauge makes it straightforward to identify non-conforming threads during routine inspections, reducing rework and ensuring parts fit correctly in mating assemblies.

• Durable hardened steel construction: Built to withstand daily use in busy workshops and production lines, offering excellent wear resistance and long service life in demanding environments.
• Precise metric fine (M65 x 2, 4h) NoGo tolerance: Calibrated to the exact external thread size, enabling fast Go/No-Go verification and reliable detection of out-of-tolerance parts to keep returns and rejects to a minimum.
• Ergonomic, user-friendly design: Knurled edge and compact form provide a secure grip and quick handling, even with gloves, speeding up routine checks and reducing inspection time.

This gauge helps you streamline quality control by delivering repeatable, reliable checks that support proper assembly, minimize downtime, and improve overall production accuracy across machining, assembly, and inspection tasks.
