The JBO Thread Ring Gauge (GO) is a metric fine go gauge designed for Right Hand threads in the M11 x 1 size (6e class). Built to verify external thread diameters quickly and reliably, it helps quality control teams, machinists, and engineers confirm that threaded components meet exact standards before production proceeds.

• Precise Go Gauge for Metric Fine M11 x 1 Threads: Quickly determine if a part’s external thread diameter falls within the GO limit, speeding up inspections and reducing guesswork.
• Hardened Steel Construction: Delivers exceptional wear resistance and long service life in demanding workshop environments, preserving accuracy over time.
• User‑Friendly, Quick‑Identify Design: Clear, straightforward use enables rapid confirmation of conforming parts, helping minimize downtime and streamline quality checks.

Designed to support reliable QC workflows and precision engineering, this gauge helps you maintain tight tolerances, shorten inspection cycles, and deliver consistent results across assemblies. With its robust construction and clear performance signals, you can trust it to improve inspection confidence and overall workflow efficiency.
