The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6e - M55 x 1.5 is a precision inspection tool designed to verify external thread sizes on fasteners, shafts, and threaded components. Ideal for engineers, inspectors, machinists, and maintenance teams, it helps you confirm that parts meet exact size and pitch specifications with quick, reliable checks. Crafted for durability, this GO gauge supports everyday use in workshops, production floors, and service environments.

• Precise metric fine-thread sizing (M55 x 1.5): Enables fast, reliable verification of external threads to the exact size and pitch required, helping you confirm compatibility and maintain consistent quality.
• Durable hardened steel construction: Built to withstand daily wear, resist corrosion, and maintain accuracy over many inspections in demanding work settings.
• Right-hand, 6e tolerance compatibility: Specifically designed for common right-hand threads within the 6e tolerance class, delivering repeatable, trustworthy checks across typical fasteners and components.

This gauge simplifies quality control by providing an immediate indication of conforming parts, reducing guesswork and rework. Its robust construction and precise sizing make it a reliable companion for manufacturing, assembly, and maintenance workflows, helping you keep production moving and parts interoperable with confidence.
