The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to verify exterior metric threads quickly and reliably. It’s ideal for engineers, machinists, inspectors, and quality teams who need to confirm that threaded components meet exact size and pitch requirements without guesswork. This metric-fine gauge is built for right-hand threads and aligns with the M145 x 2 specification to support accurate Go/NoGo checks in everyday workflows.

• NoGo verification for fast conformance: Enables immediate pass/fail decisions on thread size, helping you spot out-of-tolerance parts at a glance and reduce inspection time.
• Fine metric sizing: M145 x 2: Specifically matched to common fine-pitch external threads, delivering accurate, repeatable checks that support tight quality control limits.
• Hardened steel construction with durable finish: Built to endure frequent use in demanding environments while maintaining long-term accuracy and reliability.

With the JBO Thread Ring Gauge NoGo, you gain consistent, dependable thread verification that streamlines inspections, improves part fit during assembly, and helps your team maintain precise standards across production and QC processes.
