The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M120 x 1.5 is a precision inspection tool designed to quickly verify external thread diameters to metric fine standards. It’s ideal for machinists, quality teams, and engineers who need reliable go/no-go checks to confirm parts meet the M120 x 1.5 specification.

Crafted from hardened steel, this gauge delivers exceptional wear resistance and long service life in demanding workshop environments. Its right-hand configuration and 6g tolerance ensure consistent, repeatable measurements across production runs, inspections, and assemblies.

• Metric Fine GO threading: Provides precise go/no-go verification for external threads to the M120 x 1.5 specification, speeding up inspections and reducing guesswork.
• Hardened steel construction: Delivers outstanding durability and wear resistance for reliable performance in busy shops over time.
• Right-hand, 6g tolerance: Ensures consistent, repeatable measurements across parts and batches, supporting quality control and uniform results.

Using the JBO Thread Ring Gauge (GO) helps you confirm fit with confidence, streamline inspections, and maintain consistent thread quality across your production line. Its durable build reduces downtime and replacement costs, while clear GO checks support faster training and higher first-pass yields.
