The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M56 x 1 is a precision tool designed for fast, reliable verification of external thread diameters. It’s ideal for machinists, quality inspectors, and assembly teams working with metric fine threads, helping you confirm that parts conform to your required standards.

Crafted from hardened steel, this GO ring gauge delivers durability and wear resistance for rigorous, daily use in busy workshops. Its exact dimensions and straightforward design make it easy to identify when a thread conforms to M56 x 1, supporting efficient quality control across the production line.

• Precise GO check for M56 x 1 external threads: Provides a reliable go/no-go assessment to confirm diameter and pitch meet metric fine standards, speeding up quality inspections and reducing measurement guesswork.
• Hardened steel construction for long life: Withstands wear and corrosion in busy environments, maintaining accuracy after repeated use and reducing maintenance and replacement costs.
• Right-hand, metric fine design for consistent compatibility: Matched to standard right-hand threads and 4h tolerance, ensuring repeatable results across parts, tooling, and suppliers.

This gauge helps you streamline inspection workloads, shorten setup and check times, and improve overall quality. By enabling quick, confident decisions on whether threads conform, it reduces rework, protects dimensional integrity, and supports reliable performance across production runs.
