The JBO Thread Ring Gauge (GO) – Metric Coarse, Right Hand, M2.5 x 0.45 is a precision inspection tool used to verify external metric coarse threads. Its hardened steel construction and knurled exterior provide durability and a secure grip for fast, repeatable go/no-go checks on parts during quality control and assembly.

• Precise metric coarse size for right-hand threads: Directly confirms the M2.5 x 0.45 external thread dimensions, enabling quick, confident pass/fail decisions in production and inspection workflows.
• Hardened steel construction: Built to resist wear and maintain gauge geometry through frequent use, delivering consistent accuracy over time in demanding shop environments.
• Ergonomic knurled grip: Textured outer surface ensures a secure, comfortable hold and fast alignment, even when wearing gloves or working in tight spaces.

This GO ring gauge helps you streamline quality checks, reduce rework, and ensure every threaded component meets standard specifications. With its robust build and precise sizing, it supports reliable assembly, repeatable results, and confidence across engineering, manufacturing, and maintenance applications.
