The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric threads. It’s ideal for engineers, inspectors, machinists, and quality teams who need quick, reliable checks of threaded components to ensure proper fit and function.

This NoGo gauge is tailored for metric fine threads: M12 x 0.75, right-hand, 6g. Crafted from hardened steel, it delivers long-lasting accuracy and wear resistance in busy shop environments, helping you maintain consistent measurement performance over time.

• Precise NoGo Verification for Metric Fine Threads: Quickly confirm that external threads meet the required maximum-material-condition standard for M12 x 0.75 (6g) right-hand threads, helping you identify out-of-spec parts before they move to the next production stage.
• Durable Hardened Steel Construction: Built to withstand daily use in demanding environments, delivering reliable performance and a longer service life even after repetitive measurements.
• Intuitive, Quick-Check Design: Easy to align with the thread and interpret results, reducing inspection time and minimizing training needs for consistent, repeatable checks.

Using the JBO Thread Ring Gauge streamlines quality control, speeds up workflows, and minimizes rework by providing clear, repeatable assessments of metric fine external threads. Its robust construction and precise design give you confidence that every threaded part meets your standards from incoming inspection through final assembly.
