The JBO Thread Ring Gauge (NoGo) is a precision inspection tool used to verify the external diameter of metric fine threads. Ideal for engineers, machinists, quality inspectors, and workshop teams, it provides quick, reliable pass/fail checks on threaded components.

Crafted for metric fine threads, this NoGo gauge features the M22 x 1.5 left-hand specification with a 6g tolerance. Its hardened steel construction delivers exceptional wear resistance, ensuring accurate measurements and long life in busy production environments.

• Fast Go/NoGo verification: Provides fast pass/fail assessment for external threads, helping inspectors identify nonconforming parts at a glance and keep production moving.
• Durable hardened steel construction: Built to withstand daily shop use, resisting wear and chipping to maintain accuracy over many jobs and years.
• Metric fine-thread compatibility: M22 x 1.5 left-hand, 6g: Specifically matched to fine-thread assemblies, delivering precise, repeatable measurements across parts and batches.

Using this gauge helps streamline quality control, reduce rework, and ensure consistent results across production runs. Its rugged design and precise geometry give you confidence that every threaded part meets the specified M22 x 1.5 left-hand, 6g standard, while straightforward go/no-go checks simplify training and handoffs between operators and inspectors.
