The JBO Thread Ring Gauge (NoGo) is a precision inspection tool engineered to verify external metric threads. Designed for metric fine threads, it targets M64 x 2 with a right-hand orientation and 6h tolerance, helping quality teams quickly determine if parts meet specification.

Crafted from hardened steel, this NoGo gauge delivers long-lasting durability and wear resistance in demanding workshop environments. Its precise dimensions stay consistent through repeated use, supporting reliable go/no-go decisions and reducing rework in manufacturing and assembly processes.

• Precise NoGo verification for metric fine threads: Quickly identify out-of-tolerance external threads on the M64 x 2 right-hand size, enabling fast, accurate inspections and compliant results.
• Hardened steel construction: Built to endure daily use in busy shops, providing durable performance and sustained accuracy over time.
• User-friendly design with clear designation: Simple to read and interpret markings, making setup and quality checks straightforward and reducing training time.

Using the JBO Thread Ring Gauge (NoGo) for metric fine thread checks helps you streamline quality control, enforce standards, and minimize rework. With its durable construction and precise measurements, you can trust consistent, repeatable results across production runs and audits—keeping components moving smoothly from inspection to assembly.
