The JBO Thread Ring Gauge (GO) - Metric Fine - Left Hand - 6g - M40 x 2 is a precision go-ring gauge designed to verify external thread diameters for metric fine threads. Sized specifically for M40 x 2 left-hand threads, it helps machinists, inspectors, and buyers quickly determine if a threaded component conforms to the required minimum diameter.

Crafted from hardened steel, this gauge offers durability and wear resistance for reliable performance in demanding workshops and production environments. Its knurled outer edge provides a secure grip, enabling fast, stable go/no-go checks and smooth handling even in busy inspection stations.

• Precise GO verification for M40 x 2 left-hand threads: Quickly confirms that the external thread diameter meets the required minimum, enabling fast pass/fail decisions and reducing inspection time on each part.
• Hardened steel construction for durability: Built to withstand daily use and resist wear, maintaining accuracy and reliability through high-volume testing.
• User-friendly, fast inspection: Knurled outer surface and straightforward geometry support easy alignment and repeatable results, enhancing workflow on crowded benches and in QC stations.

With the JBO Thread Ring Gauge, you’ll streamline quality checks, minimize rework, and ensure every M40 x 2 left-hand threaded component meets exacting standards. It integrates smoothly into standard inspection routines, helping your team deliver consistent, confident results from the first part to the last.
