The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify external metric threads. Specifically tuned for right-hand M40 x 1, metric fine pitch (6e) components, it helps manufacturers and inspectors confirm that fasteners and machined parts meet exact size and fit requirements.

Crafted from hardened steel, this NoGo ring delivers durability and long life in busy workshops, resisting wear and maintaining accuracy across many inspections. Its simple, intuitive design makes it easy to identify non-conforming threads, supporting efficient quality control and precision engineering workflows.
