The JBO Thread Ring Gauge (GO) - Metric Fine - Left Hand - 6g - M78 x 2 is a precision tool used to verify external thread diameters to metric fine standards, helping ensure fit and performance across a range of components. It is ideal for inspectors, machinists, and quality teams who need quick, accurate checks against defined specifications.

Crafted from hardened steel for durability and wear resistance, this GO gauge is built to withstand demanding work environments, with an easy-to-identify design that supports fast conformance checks during routine quality control.

• Precise GO gauge for metric fine threads: Enables accurate external thread diameter checks against metric fine standards for components like M78 x 2 (6g).
• Hardened steel construction for durability: Resists wear and maintains accuracy through repeated use in busy workshops and production lines.
• Left-hand configuration for broader compatibility: Supports inspection of left-hand threaded components, increasing versatility in QC and assembly processes.

This GO ring gauge helps streamline quality control by delivering quick, reliable pass/fail results for external threads, enabling consistent assemblies and reducing rework. Its precise dimensions and durable build support precision engineering workflows, so teams can meet standards with confidence and speed.
