JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6h - M19 x 1

The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric threads. Ideal for engineers, quality teams, and workshop technicians, it helps you confirm that threaded components meet the required diameter and tolerance. With its NoGo check, you can quickly identify parts that are out of spec, supporting consistent quality across productions.

Made from hardened steel for exceptional wear resistance, the gauge delivers long-lasting accuracy in demanding environments. The metric fine size is M19 x 1, right-hand orientation, with a 6h tolerance, ensuring repeatable measurements across batches.

• Hardened steel construction: Built to withstand daily use in tough workshop settings, delivering durable, stable measurements and long tool life.
• Clear NoGo verification for fast QC: The NoGo face provides a decisive pass/fail indication, helping you quickly reject threads that are out of tolerance and keep production moving.
• Precise metric sizing: M19 x 1, right-hand, 6h tolerance: Precisely machined to exact size, ensuring consistent readings and reliable quality checks across parts and lots.

Using the JBO NoGo Thread Ring Gauge integrates seamlessly into standard quality-control workflows. It helps you validate external thread diameters early, reduce rework, and improve first-pass yields. The combination of hardened steel durability and precise M19 x 1 sizing gives you confidence in inspection results, supports compliance with standards, and promotes smoother handoffs between manufacturing and QA teams.
