The JBO Thread Ring Gauge (NoGo) is a precision tool designed for checking external metric fine threads. It is tailored for right-hand threads in the metric fine series, specifically M1.4 x 0.2 with a 6h class, making it ideal for technicians, machinists, engineers, and quality inspectors who need quick, reliable diameter checks on threaded parts. Crafted to deliver consistent results, it helps ensure components meet defined standards during inspection.

Built from hardened steel, this gauge offers outstanding wear resistance and long-lasting performance in demanding shop environments. Its straightforward design makes it easy to identify non-conforming threads at a glance, supporting efficient quality control and reducing the need for rework.

• Precision metric fine threading compatibility (M1.4 x 0.2, 6h, Right Hand): ensures accurate verification of external thread diameters against exact metric fine specifications.
• Hardened steel construction: delivers durability and wear resistance for reliable use in busy workshops and over many inspections.
• Fast NoGo verification for quality control: enables quick pass/fail decisions, helping to identify non-conforming parts and keep production moving smoothly.

In everyday use, this gauge supports consistent, confident quality checks, minimizes downtime, and helps you maintain tight tolerances across production runs. Its robust build and precise dimensions give you dependable measurements you can trust from inspection through final assembly.
