The JBO Thread Ring Gauge (NoGo) is a precision tool for inspecting external metric threads. Designed for right-hand, metric-fine thread applications, it uses a NoGo configuration to quickly verify M30 x 1.5 threads meet the required tolerance.

Made from hardened steel for durability, this gauge resists wear in demanding workshops. Its knurled outer edge and precisely machined threads ensure smooth insertion and reliable alignment, delivering consistent inspections across batches.

• Quick Pass/Fail Go-NoGo Checks: Enables fast, unambiguous verification of external threads so inspectors can identify out-of-tolerance parts at a glance and keep production moving.
• Durable Hardened Steel Construction: Built to withstand daily use in busy environments, providing long service life and stable measurements over time.
• Metric Fine, Right-Hand 6e, M30 x 1.5 Compatibility: Specifically matched to the metric fine thread class and size, ensuring reliable measurements and easy integration into existing inspection workflows.

Using the JBO Thread Ring Gauge helps you streamline quality control, reduce rework, and improve overall threading performance. With durable construction and precise dimensions, you can trust repeatable results across parts and shifts, improving workflow and confidence in every measurement.
