The JBO Thread Ring Gauge (GO) - Metric Fine - Left Hand - 6g - M24 x 1.5 is a precise go/no-go tool designed to verify external thread diameters and pitch. Built for machinists, inspectors, and manufacturers, it helps confirm that threaded components meet the exact metric fine standard and 6g tolerance. Whether you’re in production, maintenance, or quality control, this gauge delivers quick, reliable checks with minimal setup.

Crafted from hardened steel for exceptional wear resistance, the GO gauge maintains accuracy through demanding use in busy workshops. The left-hand configuration broadens its applicability, enabling reliable checks on both standard and left-handed threaded parts and ensuring you can validate a wide range of components with confidence.

• Metric Fine M24 x 1.5 Go Gauge: Designed for precise go/no-go checks of fine-pitch metric threads, enabling quick verification that parts meet the M24 x 1.5 specification and pass inspection.
• Left-Hand Thread Compatibility: Supports inspection of left-handed threaded components, expanding usability across diverse applications and enabling faster setup for reverse-thread fasteners.
• Durable Hardened Steel Construction: Built to withstand daily use in demanding environments, delivering long tool life and stable, repeatable measurements over time.

This gauge simplifies quality control by delivering clear, repeatable results that technicians can trust. It helps reduce rework and downtime, speeds up the inspection process, and supports consistent thread quality across parts and batches. Use it to verify fit, ensure standards compliance, and maintain efficiency in machining, assembly, and maintenance workflows.
