The JBO Thread Ring Gauge (NoGo) is a precision inspection tool designed to quickly verify external metric fine threads. Built for engineers, machinists, quality teams, and workshop technicians, it helps ensure threaded components meet the exact sizing and tolerance required for reliable mating and performance. This NoGo gauge is configured for right-hand threads and sized M120 x 3 with a 6g tolerance, making it ideal for common precision assemblies.

Crafted from hardened steel, this gauge delivers exceptional durability and wear resistance to stand up to busy work environments. Its robust construction supports repeatable measurements during routine QC checks, while the user-friendly design makes it easy to identify non-conforming parts at a glance, helping prevent misfits and speed up downstream processes.

• Fast NoGo verification for metric fine threads: Quickly confirm external threads are within tolerance, enabling rapid rejection of out-of-spec parts and reducing inspection time.
• Durable hardened steel construction: Built to withstand frequent use and contact with threaded components, maintaining accuracy and delivering long service life in demanding environments.
• Right-hand, M120 x 3 sizing (6g) for broad compatibility: Covers a common metric fine-thread size range, simplifying tool inventory and ensuring reliable checks across typical assemblies.

Using the JBO NoGo Thread Ring Gauge improves workflow by speeding up inspection, reducing rework, and delivering consistent results across batches. Its durable build and precision design give you confidence in every measurement and a smoother path from inspection to final assembly.
