The JBO Thread Ring Gauge (GO) – Metric Fine, Right Hand, 6e, M18 x 2 is a precision Go gauge used to verify external thread diameters. Designed for quality-control teams, machinists, and maintenance professionals, it helps confirm that threaded parts meet exact size and pitch specifications.

Crafted from hardened steel for durability, this ring gauge resists wear in busy workshop environments and high-volume inspection routines. The GO gauge clearly indicates conforming parts, making pass/fail decisions fast and reliable for metric fine thread standards like M18 x 2 (6e) on right-hand threads.

• Precise Go verification for metric fine threads: Quickly confirm external threads such as M18 x 2, 6e, on right-hand hardware, reducing guesswork and rework during inspection.
• Rugged hardened steel construction: Built to endure daily use in demanding workshops, delivering long service life and stable measurements.
• Clear pass/fail indication for fast, confident inspections: The GO gauge clearly shows when a thread matches the standard, speeding up QC checks and minimizing bottlenecks on the line.

This ring gauge helps streamline threading inspections, minimize downtime, and improve consistency across parts and assemblies. By providing a reliable, durable tool for confirming thread size and pitch, it supports precise assembly, quality control, and maintenance workflows—giving you confidence that every threaded connection meets required standards.
