JBO Thread Ring Gauge (NoGo) - Metric Fine - Right Hand - 6g - M40 x 2 is a precision external thread inspection tool designed to verify the size and tolerance of metric fine threads on fasteners and components. It is ideal for engineers, machinists, quality inspectors, and maintenance teams, helping you quickly confirm whether a part’s external threads meet the required specifications.

Crafted from hardened steel for durability and wear resistance, the NoGo ring gauge delivers reliable performance in busy workshop environments. Its right-hand orientation and 6g class ensure consistent measurements for M40 x 2 threads, while the straightforward design makes it easy to identify non-conforming parts during routine quality checks, reducing downtime and rework.

• Go/NoGo style verification: Provides clear feedback on whether external threads exceed the maximum limit, enabling rapid pass/fail decisions and reducing inspection time.
• Hardened steel construction: Built to endure daily use in demanding environments, resisting wear to maintain accuracy over time.
• Metric fine, M40 x 2, right-hand, 6g tolerance: Precisely matched to the target thread profile for consistent measurements across parts and batches.

With the JBO NoGo ring gauge, you gain a reliable, repeatable method to verify thread diameters, streamline quality control, and protect your production line from faulty components. Its durable construction and precise sizing support faster inspections, fewer rework cycles, and more consistent results across every batch, giving your team confidence in every measurement and every part you ship or assemble.
