The JBO Thread Ring Gauge (GO) in Metric Fine, Right Hand, 6g, M18 x 1.5 is a precision inspection tool designed to verify external thread diameters. It helps engineers, machinists, quality inspectors, and maintenance teams quickly confirm that threaded components meet the Go limit for the M18 x 1.5 coarse/fine thread standard.

Crafted for durability and consistent results, this GO ring gauge features a fine-pitch metric thread and a robust hardened steel body. Its precise sizing and smooth, machined surfaces support reliable inspections in busy workshops, ensuring components conform to required specifications.

• Metric Fine Go Gauge for M18 x 1.5: Quickly verify external thread diameter against the Go limit, enabling fast pass/fail decisions and reducing inspection time.
• Hardened steel construction: Withstands daily wear, resists corrosion, and maintains accuracy for long service life in demanding environments.
• Right-Hand, 6g tolerance: Aligns with standard fine-thread specs for reliable, repeatable checks across batches and different parts.

Using this gauge helps streamline quality control, shorten inspection cycles, and minimize rework by catching out-of-tolerance parts early. Its rugged build and clear go/no-go result give you confidence on the shop floor, whether you’re setting up a machine, performing incoming inspection, or validating threaded components in assemblies.
