The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external threads on components with metric fine pitch. Specifically built for M42 x 1 right-hand threads and 6h tolerance, this gauge helps quality teams, engineers, machinists, and inspectors quickly confirm whether a part meets the required dimensional standards. Its NoGo design provides a simple pass/fail indication, streamlining your gauging workflow.

Crafted from hardened steel with tight dimensional control, the gauge resists wear in busy workshops and maintains accurate measurements over time. The robust construction supports frequent use in production lines, maintenance shops, and quality labs, while the clear NoGo check makes it easy to identify threaded parts that exceed allowable tolerances.

• Exact Metric Fine Thread: M42 x 1, Right-Hand, 6h: Precisely machined to the specified external thread size with the correct orientation and tolerance class, ensuring consistent and reliable checks across parts and setups.
• NoGo Quick-Check for Fast QC: The NoGo limit provides an instant pass/fail result, reducing inspection time and helping you keep production moving without guesswork.
• Durable Hardened Steel Construction: Built to withstand daily use in shop environments, resisting wear while preserving measurement integrity and long-term accuracy.

With the JBO Thread Ring Gauge, your team gains a dependable tool that simplifies thread validation, shortens inspection cycles, and supports consistent output across batches. By catching non-conforming threads early, it reduces downtime, rework, and scrap, while its solid construction gives you confidence to rely on it daily in QA, manufacturing, and repair workflows.
