The JBO Thread Ring Gauge (NoGo) is a precision external-thread gauge designed for metric fine sizes. It’s specifically configured for right-hand M102 x 2 threads and functions as a NoGo check to ensure your parts don’t exceed the maximum allowed diameter. Weighing just 6 g and built from hardened steel, this gauge delivers reliable performance in busy workshops, inspection labs, and production lines.

Its compact form and durable construction let you perform quick, repeatable checks on threaded components, helping you maintain consistent quality across lots and operators.

• Durable hardened steel construction: Built to withstand daily use in machining and assembly environments, delivering long service life and stable measurements.
• Precise metric fine sizing for M102 x 2 right-hand threads: Accurate NoGo sizing that helps confirm components meet the required maximum diameter, reducing tolerance-related rejects.
• Clear, quick-pass/no-go evaluation: Ring gauge design and labeling enable fast interpretation of results, speeding up inspections and decision-making.

Using the JBO NoGo ring gauge integrates smoothly into your QC workflow. It provides a simple, dependable method to confirm thread compatibility and dimensional compliance, helping you reduce rework, shorten inspection times, and maintain consistent results across production runs.
