The JBO Thread Ring Gauge (NoGo) – Metric Coarse, Right Hand, 6h, M2 x 0.4 is a precision inspection tool designed to verify external thread diameters against the NoGo limit. Ideal for quality control labs, machine shops, engineering teams, and manufacturing lines, it provides fast, reliable pass/fail checks to confirm metric coarse threads meet exacting standards.

Crafted from hardened steel for exceptional durability, this gauge stands up to daily use in demanding environments and resists wear over time. Its clear NoGo design makes it easy to identify non-conforming parts at a glance, helping you maintain consistent quality and reduce rework across batches.

• NoGo sizing for quick conformance checks: Quickly determine whether a threaded part violates the maximum limit, enabling fast pass/fail decisions and streamlined inspections.
• Durable hardened steel construction: Built to withstand tough shop-floor use with long tool life and reliable performance, even after repeated handling and measurements.
• Metric Coarse calibration for M2 x 0.4, Right Hand, 6h: Precisely matched to standard metric coarse threads, ensuring accurate measurements and reliable fitment across common fasteners and assemblies.

Used in precision engineering and quality-control workflows, this gauge helps you deliver consistently accurate parts, speed up inspections, and reduce the risk of mismatched components in your final assembly.
