The JBO Thread Ring Gauge (GO) is a metric fine-thread Go gauge designed to quickly verify external thread diameters against the M52 x 1 standard. It’s ideal for inspectors, machinists, and quality teams who need fast, reliable confirmation that threaded parts meet spec.

Made from hardened steel for durability, this right-hand, 6h-profile gauge provides clear, repeatable checks in busy workshops and precision engineering environments, helping you reduce rework and speed up inspection cycles.

• Precise Go Gauge for Metric Fine M52 x 1 Threads: Enables quick pass/fail checks of external threads, helping quality control verify conformance with the M52 x 1 standard and maintain consistent results across parts.
• Hardened Steel Construction for Long Life: Provides excellent wear resistance and durability in demanding environments, reducing replacement costs and downtime.
• Right-Hand, 6h Profile for Consistent Fit: Designed to match the standard right-hand metric fine-thread tolerance, delivering repeatable measurements and fewer false rejections during inspections.

The JBO GO Gauge simplifies threaded inspection by offering a consistent, reliable measurement reference. It speeds up acceptance testing, minimizes guesswork, and supports tighter quality control, so you can improve workflow, reduce downtime, and achieve more reliable results in assembling or manufacturing processes.
