JBO Thread Ring Gauge (GO) - Metric Coarse - Right Hand - 4h - M5 x 0.8 is a precision inspection tool designed to verify external metric threads. Ideal for quality control, machining shops, and field service, it helps confirm that components will thread correctly with the M5 x 0.8 coarse pitch and meet standard fit requirements.

With a Go gauge format, users get a clear go/no-go indication during checks, enabling fast, repeatable measurements and minimizing guesswork in assembly and mating operations.

• Go/No-Go verification at a glance: Quickly confirm if the external thread meets the M5 x 0.8 coarse pitch with a right-hand thread, reducing inspection time and ensuring correct fit.
• Hardened steel construction: Built from hardened steel for excellent wear resistance and long life in daily shop use, maintaining dimensional accuracy over time.
• Consistent, repeatable measurements: Precision-engineered to standard 4h tolerance for metric coarse threads, enabling reliable checks across components and batches.

Using this gauge helps streamline your inspection workflow, reduces rework, and ensures mating parts assemble correctly the first time. Its durable construction and precise geometry support high-volume QC, lowering downtime and helping you meet quality standards with every lot.
