The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric threads on fasteners, shafts, and fitted components. Ideal for engineers, quality inspectors, machinists, and workshop crews, it helps confirm that threads meet exact standards without guesswork.

Crafted from hardened steel for lasting performance, this NoGo gauge is built to endure daily use in demanding environments. Its precise dimensions and metric fine configuration (M115 x 2) support quick, clear conformance checks and reliable identification of out-of-spec parts.

• Durable hardened steel construction: Built to withstand daily workshop use, resisting wear so measurements stay reliable over time.
• Metric Fine NoGo sizing for fast conformance checks: Precisely calibrated for M115 x 2 metric fine threads, enabling quick pass/fail decisions and reducing inspection time.
• Right-hand orientation for standard use: Designed for common right-hand threads, easing integration into existing inspection workflows and reducing setup errors.

The JBO Thread Ring Gauge helps you verify external threads quickly and reliably, improving quality control and reducing scrap. Its durable construction and precise sizing support long-term accuracy, minimizing downtime and enabling consistent results across production runs.
