The JBO Thread Ring Gauge (GO) – Metric Fine is a precision tool designed to verify external thread diameters quickly and reliably. Ideal for engineers, machinists, inspectors, buyers, and hobbyists, it helps ensure threaded components meet the M140 x 2 right-hand thread standard with confidence and consistency.

• Metric Fine GO gauge for M140 x 2 threads: Quickly confirm that a component’s external thread diameter meets the GO limit, speeding inspections and reducing guesswork in quality control.
• Hardened steel construction for durability: Built to withstand everyday workshop use, resisting wear and maintaining accuracy for long service life in demanding environments.
• Right-hand orientation with 6g tolerance: Aligns with standard right-hand thread forms and precise tolerance, enabling reliable, repeatable measurements across jobs.

Using this gauge supports fast, confident decisions in machining, assembly, and quality assurance. It helps streamline workflows, reduces inspection time and rework, and provides consistent results that improve overall manufacturing quality and component reliability.
