The JBO Thread Ring Gauge (NoGo) provides a precise check of external thread diameters to the Metric Fine standard. Specifically configured for Right Hand threads (6g) on M118 x 1.5, this NoGo gauge helps engineers, machinists, inspectors, and hobbyists quickly confirm whether threaded parts meet exact tolerances or require adjustment, reducing guesswork in quality control.

• Accurate Metric Fine NoGo verification: Delivers consistent pass/fail results for external threads at M118 x 1.5 (6g), helping validate component compliance and streamline quality checks.
• Hardened steel construction for durability: Designed to withstand frequent use in demanding workshops, resisting wear and maintaining accurate dimensions for long service life.
• User-friendly inspection workflow: Simple ring design and clear referencing make it easy to identify non-conforming parts quickly, reducing downtime and rework.

This gauge enables you to tighten your quality control processes, improve consistency across parts, and speed up threaded assembly tasks. With reliable sizing and durable construction, it reduces waste, protects tool investments, and supports confident decisions in production, maintenance, and engineering projects.
