JBO Thread Ring Gauge (GO) - Metric Fine - Right Hand - 6e - M78 x 1.5

The JBO Thread Ring Gauge (GO) - Metric Fine, Right Hand, 6e, M78 x 1.5 is a precision inspection tool used to verify external thread diameters. It helps engineers, machinists, and quality teams quickly confirm that parts with M78 x 1.5 right-hand threads meet the exact GO size and pitch requirements, ensuring consistent fit and performance across assemblies.

Crafted from hardened steel for durability, this GO ring gauge resists wear in busy workshops and delivers dependable, repeatable measurements through everyday use in manufacturing, repair, and quality-control environments.

• Fast pass/fail inspection: The GO size lets you quickly confirm which parts meet the required external thread diameter, speeding up quality checks and reducing rework.
• Durable hardened steel construction: With excellent wear resistance, it stands up to daily handling and repeated use, maintaining accuracy over time.
• Metric fine compatibility with M78 x 1.5 – Right Hand 6e standard: Precisely matched to the target thread spec, delivering reliable, consistent measurements and simplifying shop documentation.

This gauge helps you streamline threading checks, cut inspection time, and improve overall quality. By providing a clear, single-go reference for conforming threads, it minimizes downtime, reduces rework, and supports repeatable results across parts and operators. Its rugged build and precise design give you confidence in every measurement, whether you're setting up a new job, performing routine QA checks, or validating incoming components.
