The JBO Thread Ring Gauge (GO) – Metric Fine – Left Hand – 6g – M25 x 1.5 is a precision inspection tool designed to verify external thread diameters and pitches. It’s ideal for engineers, machinists, quality inspectors, and shop-floor teams who need fast, reliable checks to ensure components conform to the M25 x 1.5 metric fine standard.

Manufactured from hardened steel, this GO ring gauge delivers durability and long service life in busy workshops. The left-hand, 6g design ensures compatibility with left-handed threaded components and tight tolerance requirements, helping you maintain consistent quality across parts and assemblies.

• Precise metric GO gauge: Enables fast, reliable checks of external thread diameters and pitch against the M25 x 1.5 metric fine standard, delivering clear pass/fail results during inspection.
• Durable hardened steel construction: Built to resist wear and maintain accuracy through daily use in demanding environments, ensuring long service life and consistent performance.
• Left-hand, M25 x 1.5, 6g compatibility: Specifically designed to match left-hand threaded components within the 6g tolerance class, reducing misfit, rework, and guesswork during assembly checks.

Using this gauge helps streamline quality control and enhance workflow. It provides quick, repeatable measurements that support compliance with standards, minimizes downtime due to failed components, and gives inspectors confidence during audits. With its robust build and precise design, the JBO Thread Ring Gauge becomes a reliable part of your measurement toolkit for manufacturing, machining, and repair contexts.
