The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 4h - M50 x 1.5 is a precision inspection tool designed to verify external thread diameters on fasteners and threaded components. It helps machinists, inspectors, and engineers quickly confirm that parts match the exact metric fine standard for reliable mating and consistent performance.

Manufactured from hardened steel for lasting durability, this GO gauge stands up to daily use in busy workshops. Its straightforward, you-can-use-it design enables fast conformance checks, helping identify properly threaded components at a glance and speeding up quality control workflows.

• Go-side accuracy for Metric Fine threads: Quickly verify external thread diameter against the M50 x 1.5 standard, enabling fast pass/fail decisions and preventing mismatches in assembly.
• Hardened steel construction for durability: Built to resist wear and impact, maintaining accuracy and extending service life in demanding environments.
• Right-hand, 4h tolerance support: Designed specifically for right-hand threads with 4h tolerance, ensuring reliable conformance checks across common metric fine fits.

Using this gauge streamlines quality control by providing clear, fast confirmation of thread size, reduces downtime from misfits, enables repeatable assembly outcomes, and supports traceable measurement records for audits and compliance.
