The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M90 x 3 is a precision GO gauge designed to quickly verify external thread diameters on metric fine threads. Ideal for machinists, inspectors, and quality teams, it helps confirm parts meet the M90 x 3 specification and 6g tolerance with a simple go/no-go check.

Made from hardened steel, it is built to withstand daily use in busy workshops. Its right-hand, fine-pitch geometry ensures reliable, repeatable checks and easy identification of conforming threads, supporting efficient quality control across production runs.

• Precision GO gauge for metric fine threads: Enables fast go/no-go verification of nominal diameter and pitch for M90 x 3, speeding inspections and reducing measurement guesswork.
• Hard-wearing hardened steel construction: Resists wear, corrosion, and deformation, delivering durable performance and consistent results over many parts and cycles.
• Right-hand thread compatibility for standard applications: Designed to test standard metric right-hand threads, simplifying setup, interpretation, and reducing inspection errors.

Whether you’re performing incoming inspection, on-the-floor QC, or assembly readiness checks, this GO gauge helps you determine thread conformity quickly and confidently. The rugged steel construction withstands daily use, while its precise geometry maintains measurement integrity across batches. Integrating the JBO Ring Gauge GO into your workflow reduces downtime, minimizes rework, and delivers consistent threaded assemblies.
