JBO Thread Ring Gauge (NoGo) - Metric Fine, Right Hand, 4h, M30 x 1 is a precision tool crafted to quickly verify external thread diameters in a wide range of parts and assemblies. It’s designed for engineers, machinists, quality inspectors, and maintenance technicians who need fast, reliable go/no-go checks to ensure components meet the M30 x 1 size within the 4h tolerance. Built to withstand daily use, this ring gauge helps you confirm dimensional compliance with confidence and consistency.

• Precise NoGo verification for M30 x 1 external threads: quickly determines if a part’s external thread falls within the NoGo limit, speeding up inspections and reducing rework.
• Durable hardened steel construction: engineered for long service life in busy workshops, resisting wear and maintaining accuracy over time.
• Right-hand metric fine threading (4h, M30 x 1): ensures compatibility with standard metric components and clean integration into your existing gauging workflow.

This gauge empowers you to enhance quality control, shorten inspection cycles, and deliver consistent results across production and assembly lines. By providing clear pass/fail indications and enduring reliability, it supports faster decision-making, fewer returns, and improved overall performance in precision threading applications.
