JBO Thread Ring Gauge (NoGo) – Metric Fine – Right Hand – 4h – M64 x 1.5 is a precision tool used to check external thread interfaces. It’s designed for engineers, inspectors, machinists, and quality teams who need fast, reliable go/no-go verification to ensure components meet exact threaded specifications. Crafted from hardened steel, it withstands daily use on busy shop floors and delivers consistent measurements over time.

• NoGo Profile for Fast Conformity: Quickly determine if the external thread diameter is within spec; if the part is out of tolerance, it won’t pass the NoGo gauge, enabling immediate identification of non-conforming components and reducing inspection time.
• Hardened Steel Construction for Long Life: Built to resist wear and maintain accuracy through repeated use in demanding environments, providing dependable performance across many inspections.
• Metric Fine M64 x 1.5, 4h Right-Hand Thread: Precisely sized for fine-pitch external threads, ensuring repeatable measurements that align with standard specifications and common workshop practices.

This gauge helps streamline quality control by delivering clear, objective results that support faster decision-making, reduced rework, and improved consistency across teams. Its durable build and exacting dimensions give you confidence that every threaded part meets the required standard, making it a reliable addition to any inspection or assembly workflow.
