The JBO GO Thread Plug Gauge (Metric Fine) is a precision inspection tool designed to verify internal threads in holes. This right-hand GO gauge is calibrated for M115 x 2 threads with a 6H tolerance, helping engineers, machinists, inspectors, and buyers confirm thread quality quickly and reliably.

Crafted from hardened steel for durability, it resists wear in demanding workshop environments, delivering long-lasting, repeatable checks during quality control and precision assembly.

• Precise metric go gauge for M115 x 2 threads: Quickly confirms that a threaded hole accepts the gauge within the 6H tolerance, providing clear go/no-go results for accurate inspection.
• Hardened steel construction for durability: Built to withstand daily use in busy shops, maintaining dimensional accuracy and extending service life even in rigorous conditions.
• Ergonomic, easy-to-use design: Knurled body and straightforward form enable fast, confident checks with minimal handling errors during quality control and assembly.

Using this GO plug gauge, you can streamline inspections, ensure consistent thread quality across parts, reduce rework, and support reliable, repeatable mating of components throughout your production workflow.
