The JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6g - M4.5 x 0.5 is a precision go/no-go gauge designed to verify external thread diameters on metric fine, right-hand threaded parts. It’s ideal for engineers, machinists, inspectors, and maintenance teams that require quick, reliable conformance checks to ensure parts meet their M4.5 x 0.5 right-hand thread specifications.

Manufactured from hardened steel, this ring gauge is built for long life in demanding workshop environments. Its compact, circular form provides straightforward alignment with the male thread and lets inspectors identify properly conformed components at a glance, helping keep production moving with fewer reworks.

• Fast Go/No-Go Conformance: Quickly determine whether external threads meet the M4.5 x 0.5 metric fine right-hand specification, speeding up quality checks and reducing guesswork on the shop floor.
• Durable Hardened Steel Construction: Resists wear and maintains accuracy through repeated use, delivering dependable performance in busy production lines and field service.
• Metric Fine Right-Hand 6g Compatibility: Precisely matched to the M4.5 x 0.5 right-hand thread, with 6g tolerance to support consistent, reliable engagement and clear pass/fail results.

Using the JBO Thread Ring Gauge (GO) helps streamline your inspection workflow, delivering clear, actionable results that improve overall thread quality. Its durable construction and precise sizing support repeatable measurements, reducing downtime and ensuring components consistently meet specification during assembly, maintenance, and QC checks.
