The JBO Thread Ring Gauge (GO) – Metric Fine – Right Hand – 6e – M52 x 1.5 is a precision inspection tool for external threads. Designed for engineers, inspectors, machinists, and hobbyists, it helps quickly verify that threaded components meet the M52 x 1.5 fine-pitch standard and the 6e tolerance. Made from hardened steel, this GO gauge resists wear and maintains accuracy through demanding use.

• Fast Go/No-Go Verification: Quickly confirm whether a component’s external thread matches the M52 x 1.5 fine-pitch standard, speeding up quality checks and reducing inspection time.
• Durable Hardened Steel Construction: Built to withstand daily shop use, resisting wear and maintaining accuracy through many cycles.
• Precise Metric Fine, Right-Hand 6e Conformance: Designed to the M52 x 1.5 fine-pitch with 6e tolerance for consistent, reliable measurements across parts and assemblies.

This gauge supports streamlined quality control and assembly processes by delivering clear, repeatable results. Its combination of precise sizing, rugged materials, and user-friendly design helps you minimize downtime, improve measurement reliability, and confidently qualify threaded components for production or repair projects.
