The JBO Thread Ring Gauge (GO) - Metric Fine, Right Hand, 4h, M30 x 1.5 is a precision go gauge designed to verify external thread diameters on threaded components. It helps manufacturers, machinists, inspectors, and technicians quickly confirm that parts meet the required thread size and pitch, supporting accurate assembly and robust quality control.

Crafted from hardened steel, this GO ring gauge delivers durable wear resistance and long service life in demanding workshop environments. Its straightforward design makes it easy to use for both seasoned inspectors and occasional users, providing clear indications when a component conforms to the M30 x 1.5 metric fine right-hand standard and reducing guesswork during inspection.

• Quick Go/No-Go Verification: Quickly determine if a part's external thread diameter meets the M30 x 1.5 metric fine right-hand standard, speeding up inspections and reducing handling time.
• Hardened Steel Durability: Constructed from hardened steel to resist wear, ensuring reliable performance across many cycles in busy production environments.
• Metric Fine Thread Compatibility: Designed specifically for M30 x 1.5 metric fine, right-hand threads (4h), delivering consistent measurements and repeatable results for parts manufactured to this standard.

Using the JBO GO ring gauge simplifies thread verification, minimizes rework, and supports tighter quality control across assemblies. It delivers fast, repeatable checks that help you maintain fit and function, shorten inspection cycles, and preserve high production yields. With durable construction and a clear go/no-go indication, you can trust this gauge to keep your threaded components matching specification from first part to last.
