The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric threads. Built for metric fine threads in a right-hand configuration, it's ideal for machinists, inspectors, and quality teams who need fast, reliable verification.

This NoGo gauge targets M76 x 6 with a 6g tolerance class, delivering quick go/no-go validation to confirm components meet the required diameter and tolerance.

• Fast pass/fail checks: The NoGo design provides immediate visibility of non-conforming threads, speeding up inspections and reducing guesswork.
• Metric fine thread compatibility: Precisely sized for M76 x 6, right-hand threads, ensuring accurate size verification and consistent results across parts.
• Durable hardened steel construction: Built to withstand daily use in demanding environments, delivering wear resistance and long service life for reliable performance.

When integrated into your inspection routine, this gauge helps you catch out-of-tolerance components before they proceed to assembly, minimize rework and scrap, and improve workflow consistency. Its straightforward go/no-go checks empower operators of all experience levels to achieve repeatable, high-quality thread measurements with confidence.
