The JBO Thread Ring Gauge (GO) - Metric Fine - Left Hand - 6g - M25 x 1 is a precision inspection tool used to verify the external thread diameter of threaded components quickly and reliably.

Crafted from hardened steel for exceptional wear resistance, this GO gauge is designed for left-hand metric fine threads and stands up to daily use in demanding workshop environments, helping teams maintain tight tolerances and consistent assembly quality.

• Precise GO gauge for M25 x 1, 6g metric fine threads: Enables fast, go/no-go checks to confirm external threads meet the specified diameter and tolerance, reducing inspection time and avoiding costly rework.
• Left-hand thread compatibility: Specifically calibrated for left-hand thread applications, ensuring correct acceptance criteria and reliable measurements in mixed-thread setups.
• Hardened steel construction: Built to endure daily use with excellent wear resistance, maintaining accuracy over many inspections and long service life in busy workshops.

This gauge supports streamlined quality control across incoming inspection, in-process checks, and maintenance work. By delivering straightforward, repeatable verification of thread conformity, it helps your team speed up workflows, reduce downtime, and improve the reliability of threaded assemblies.
