The JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 4h - M25 x 1.5 is a precision tool designed to verify external thread diameters on components with metric fine threads. Its NoGo design provides a straightforward pass/fail check that helps you identify out-of-spec threads during routine inspections, speeding up quality control on fasteners, fittings, and machined parts.

Manufactured with hardened steel for durability, this gauge stands up to busy workshop conditions and repeated use. The Right-Hand, Metric Fine configuration is tailored to M25 x 1.5 threads and the 4h tolerance, delivering reliable, repeatable checks that support consistent manufacturing quality and adherence to standards.

• Fast Go/No-Go checks: Quickly determine whether a threaded component meets the required diameter, reducing inspection time and the risk of deploying non-conforming parts.
• Durable hardened steel construction: Built to resist wear in demanding environments, delivering long service life and stable, repeatable measurements.
• Metric Fine, M25 x 1.5, Right-Hand with 4h tolerance: Precisely matched to the target thread size and orientation, ensuring accurate checks that support consistent quality control across batches.

Using the JBO Ring Gauge helps streamline inspections, minimize downtime from rejects, and improve overall precision in thread assembly. Its combination of toughness, tailored sizing, and simple operation supports faster workflows and greater confidence in every measurement.
