The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M23 x 0.75 is a precision tool designed to verify external thread diameters on threaded components. It helps inspectors, machinists, and manufacturers quickly confirm parts meet the required dimensional standards during quality control and assembly work.

Crafted from hardened steel, this GO ring gauge offers durability under daily workshop use, resisting wear and maintaining accuracy over time. Its metric-fine thread profile and clear GO indication make it easy to identify correctly machined parts, streamlining inspections in metalworking, automotive, and manufacturing environments.

• Precise GO verification: Confirms external thread diameters against the M23 x 0.75 fine pitch standard, enabling reliable pass/fail decisions during quality checks.
• Hardened steel construction: Built to resist wear and corrosion in demanding environments, helping maintain accuracy and extending tool life.
• Easy to use in QA workflows: Simple, intuitive design speeds inspections, reduces downtime, and supports consistent threading tolerances across lots.

This gauge helps you tighten control over thread quality, accelerate inspection cycles, and improve overall thread-fit results. By delivering dependable, repeatable measurements, it supports safer assemblies, fewer rejections, and smoother production flows from setup to final QA.
