The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed for metric coarse threads. It helps quality teams, engineers, machinists, and maintenance staff quickly verify external thread diameters, ensuring components meet the M2.5 x 0.45 standard. This NoGo gauge is ideal for standardizing fit and function across parts in manufacturing and repair environments.

Crafted from hardened steel for lasting durability, this gauge stands up to daily use, wear, and cleaning in busy workshops. Its straightforward NoGo design makes it easy to identify non-conforming threads, while the right-hand orientation and defined 6h specification provide reliable, repeatable checks across applications.

• Precise NoGo verification for metric coarse threads: Quickly confirm whether an external thread exceeds the maximum size, enabling fast, accurate pass/fail decisions and reducing inspection time.
• Durable hardened steel construction: Built to withstand demanding environments, delivering long tool life and consistent measurements with minimal maintenance.
• Right-hand orientation and M2.5 x 0.45 compatibility: Specifically matched to the metric coarse thread standard, ensuring reliable checks and repeatable results every time.

Using the JBO Thread Ring Gauge (NoGo) streamlines quality control, minimizes rework, and supports confident decisions on part readiness. It helps maintain consistent thread fit across production runs and service projects, delivering dependable performance in a compact, easy-to-use tool.
