The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M10 x 1 is a precision GO gauge designed to verify external threads on fasteners, fittings, and machined parts. It’s ideal for engineers, machinists, inspectors, and quality teams who need a reliable, fast check that a thread meets the M10 x 1 metric fine standard with a 4h tolerance.

Built for the demands of busy workshops, this GO gauge is crafted from hardened steel to resist wear and maintain dimensional accuracy over extended use. Its straightforward design makes it easy to identify properly conforming threads, helping quality teams speed up inspections and keep production moving.

• Precise GO verification for metric fine threads: Quickly confirm external thread diameter and pitch alignment with M10 x 1, 4h tolerance, enabling fast, reliable pass/fail decisions in inspection.
• Rugged hardened steel construction: Designed to withstand daily shop use, resisting wear and deformation to preserve accuracy and extend tool life in demanding environments.
• Intuitive, user-friendly design for quick checks: Clear form and accessible bore allow for fast, repeatable measurements, reducing inspection time and human error.

Using the JBO GO thread ring gauge helps you streamline thread inspections, reduce rework, and improve overall part quality. It supports faster throughput in manufacturing and maintenance while delivering consistent results for compliant assemblies and reliable performance in the field.
