The JBO Thread Ring Gauge (GO) for Metric Fine threads is a precision inspection tool designed to verify external thread diameters quickly and accurately. It’s ideal for machine shops, production lines, and quality teams that rely on reliable go/no-go checks to confirm thread size and fit.

Specifically configured for left-handed threads (M72 x 1.5, 6g) and built from hardened steel for lasting durability in demanding environments, the ring features a knurled outer edge for a secure grip and fast setup, supporting repeatable measurements.

• Go gauge for metric fine left-handed threads (M72 x 1.5, 6g): Quick, go/no-go verification of the external thread diameter and pitch, helping ensure parts meet exact specifications with minimal downtime.
• Hardened steel construction for durable longevity: Resists wear under heavy use, preserving tight tolerances and reducing replacement costs over time.
• Knurled outer edge for secure grip and fast setup: Enables precise handling and easy operation, even with gloves, speeding up inspections and reducing setup errors.

When integrated into your quality workflow, the JBO GO thread gauge helps you confirm conformance at a glance, streamline inspections, and deliver consistent, reliable results across batches. With its robust build and exacting dimensions, it supports precise engineering, reduces rework, and gives your team confidence in every measurement.
