The JBO Thread Ring Gauge (GO) - Metric Fine - Left Hand - 6g - M28 x 2 is a precision tool designed to streamline external-thread inspection. It helps engineers, machinists, inspectors, and fabricators quickly verify that metric fine threads conform to the M28 x 2 standard, ensuring reliable fit and performance across components.

Crafted from hardened steel, this GO thread ring gauge delivers exceptional durability and wear resistance for demanding workshop environments. Its left-hand configuration is specifically tailored for left-hand threaded parts, with a 6g tolerance that supports consistent, repeatable go/no-go checks and easy identification of properly conforming components.

• Rugged hardened steel construction: Built to withstand daily use in busy shops, this gauge maintains accuracy over time and reduces replacement needs.
• Precise metric fine GO gauge for M28 x 2: Machined to exact specification, it delivers fast, confident checks that parts meet size and pitch requirements.
• Left-hand design with 6g tolerance: Designed for left-hand threads and a 6g grade, providing reliable, consistent results across production runs.

Using the JBO GO gauge simplifies quality control by delivering quick, decisive checks that speed up inspections, cut rework, and help you achieve consistently accurate threaded assemblies in less time.
