The Asimeto Ring Thread Gauge (NoGo) is a metric, right-hand gauge engineered for precise inspection of M5 x 0.35 threads to the 6g tolerance class. Designed for machinists, quality engineers, and maintenance teams, it provides a clear pass/fail check to verify correct thread size before assembly.

• 6g tolerance class: Ensures precise measurement of the thread pitch diameter within tight limits.
• NoGo designation: Quickly reveals threads that are too large by failing to pass through the gauge, signaling out‑of‑tolerance parts.
• Metric sizing: M5 x 0.35 pitch, a common small-thread specification for precision fasteners.
• Right-hand configuration: Optimized for standard right-hand thread systems in everyday applications.
• 686 Series construction: Part of the 686 Series, built for consistent performance and long service life.
• Durable materials: Crafted from high-quality materials to withstand frequent use in QA and production environments.

Using this NoGo ring gauge ensures only properly sized fasteners enter critical joints, reducing the risk of over‑ or under‑sized threads that could compromise strength and safety. It streamlines quality control with an objective, easy-to-interpret test, minimizes rework, and supports reliable assembly across manufacturing, maintenance, and repair workflows. The combination of metric M5 x 0.35 capability and durable construction makes the gauge a dependable tool for daily inspection tasks, helping teams maintain consistent thread quality over time.
