The JBO Thread Ring Gauge (NoGo) - Metric Fine is a precision tool designed for validating external thread diameters on a wide range of components. Whether you’re an engineer, machinist, quality inspector, or maintenance professional, this NoGo gauge helps you quickly confirm that a threaded part is within the specified limits.

Built for durability in busy workshops, the gauge is crafted from hardened steel to resist wear and stand up to daily use. It specifically covers metric fine threads, including M26 x 1.5, in a right-hand orientation with 6h tolerance, making it a reliable choice for precise inspections and quality control workflows.

• NoGo verification for fast, fail-proof inspections: Quickly identify oversized (non-conforming) threads, reducing rework and keeping production moving.
• Rigid, durable hardened steel construction: Withstands daily use in demanding workshop environments and maintains accuracy over time.
• Metric fine compatibility: M26 x 1.5, right-hand, 6h: Precisely matched to common fine-thread sizes, ensuring repeatable checks on standard components and minimizing setup time.

Using the JBO Thread Ring Gauge helps streamline quality control, shorten inspection time, and improve the reliability of threaded assemblies across production lots. Its rugged construction and precise sizing give you confidence that parts will assemble correctly, reducing downtime and rework while supporting consistent, high-quality results.
