The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6h, M2.5 x 0.2 is a precision inspection tool designed to verify external thread diameters quickly and reliably. Built for machine shops, manufacturers, engineers, and quality teams, it helps confirm that small metric threads meet exact limits without guesswork.

Made from hardened steel for exceptional durability, this NoGo gauge resists wear in demanding environments and maintains accurate measurements over many cycles. Its straightforward, user-friendly design makes it easy to use in daily quality checks, so you can identify non-conforming components at a glance and keep production moving.

• Precise metric fine NoGo sizing: Calibrated for M2.5 x 0.2 with 6h right-hand threads, enabling quick verification that an external thread is within the NoGo limit and flagging parts that exceed the specification.
• Durable hardened steel construction: Built to endure busy workshop use with excellent wear resistance, delivering long-lasting, stable measurements over countless inspections.
• User-friendly inspection workflow: Designed for fast, intuitive use so non-conforming parts are identified immediately, supporting efficient quality control and reliable decision-making.

With its robust design and precise dimensions, this gauge helps streamline your quality control processes—reducing inspection time, minimizing rework, and ensuring consistent results across your small-thread assemblies.
