The JBO Thread Ring Gauge (NoGo) – Metric Fine, Right Hand, 6H, M50 x 2 is a precision inspection tool designed to verify external thread diameters on fasteners and mating components. It’s ideal for quality control labs, machine shops, and maintenance teams that require quick, reliable checks to confirm parts meet metric fine thread standards. Crafted from hardened steel, the gauge resists wear and maintains accuracy under daily use, delivering long service life in demanding environments.
- Precise NoGo verification for metric fine threads: Enables fast pass/fail assessments of external threads, helping you quickly identify non-conforming parts and maintain consistent quality across batches.
- Rugged, wear-resistant construction with a secure grip: Hardened steel stands up to busy workshop use, and the knurled edge provides a secure, comfortable grip for easy handling—even with gloves.
- Right-hand metric fine threading, M50 x 2, 6H tolerance: Precisely matched to standard right-hand M50 x 2 threads with 6H tolerance, reducing guesswork and ensuring reliable compatibility with common fasteners.
Using the gauge streamlines inspection workflows by delivering clear, repeatable NoGo results, minimizing rework and assembly delays. Its durable construction means fewer replacements and less downtime, while the compact ring form keeps your metrology toolkit organized and ready for rapid checks on the shop floor.
