The JBO Thread Ring Gauge (GO) - Metric Fine is a precision tool designed to verify external thread diameters across a range of industries. It’s ideal for engineers, quality teams, machinists, and maintenance technicians who need fast, reliable checks to ensure threaded parts meet exact standards.

Designed for metric fine threads and optimized for left-hand applications, this gauge covers M26 x 2 with a 6g tolerance class. Its GO designation supports quick, confident go/no-go inspections, helping you validate component fit and consistency in busy production environments. Crafted from hardened steel, it delivers durability and long-lasting accuracy in demanding workshops.

• Precise metric fine GO gauge for LH M26 x 2: Enables fast, reliable go/no-go checks against the exact left-hand thread form, reducing inspection time and minimizing guesswork on threaded components.
• Durable hardened steel construction: Built to resist wear and maintain accuracy with heavy use, lowering calibration frequency and extending service life in busy shop floors.
• Left-hand thread compatibility for quick verification: Specifically matched to LH threads, simplifying setup and ensuring consistent results when inspecting components with reverse-rotation threading.

Using the JBO Thread Ring Gauge simplifies quality control by providing a clear, repeatable method to confirm thread size and pitch. It helps speed up inspections, improve workflow efficiency, and reduce scrap by catching out-of-tolerance parts early. The combination of precise metric fine tolerances and robust construction supports reliable performance across production runs, maintenance checks, and field service applications.
