The JBO Thread Ring Gauge (NoGo) in Metric Fine is a precision inspection tool designed to verify external thread diameters on fasteners and threaded components. Built for right-hand threads with a 6g tolerance and size M35 x 2, it helps engineers, buyers, and technicians quickly confirm parts meet exact standards. The knurled outer edge provides a secure grip during setup and handling, even when wearing gloves.

Made from hardened steel, this NoGo gauge delivers exceptional durability and wear resistance to stand up to daily use in demanding environments, ensuring reliable performance over time.

• Accurate external thread verification: Quick, reliable checks for metric fine threads (M35 x 2) to confirm parts meet the 6g class and true diameter with minimal inspection time.
• Hardened steel for durability: Built to endure heavy use on the shop floor, resisting wear, scratches, and impact for long service life.
• Clear NoGo indication for fast decisions: Intuitive design that makes it easy to identify non-conforming threads, reducing downtime and rework.

This gauge integrates seamlessly into quality-control workflows, helping you speed up inspections, improve consistency across batches, and protect your manufacturing standards. With robust construction and a user-friendly grip, it supports efficient, repeatable results in aerospace, automotive, plumbing, and general mechanical applications.
