The JBO Thread Ring Gauge (NoGo) is a precision tool designed to verify external metric coarse threads, specifically M16 x 2 on right-hand threads. It helps engineers, machinists, quality teams, and maintenance personnel quickly confirm that threaded components meet exact size and tolerance requirements.

Built for daily use in busy workshops, this NoGo gauge supports consistent inspection by clearly signaling non-conforming parts, helping your team maintain reliable fitment and reduce rework.

• M16 x 2 coarse, right-hand threads (6g): Precisely sized NoGo gauge tailored to this common metric thread, enabling fast, accurate go/no-go decisions on thread integrity and tolerance.
• Hardened steel construction: Delivers long-lasting durability and wear resistance in demanding environments, preserving accuracy over numerous inspections.
• User-friendly inspection: Simple, easy-to-interpret checks that speed up quality control and minimize the chance of accepting out-of-spec parts.

By providing quick, reliable verification of thread size and tolerance, the JBO Thread Ring Gauge helps streamline your inspection workflow, reduce downtime, and ensure consistent, high-quality assemblies across production runs and maintenance projects.
