Asimeto Ring Thread Gauge (NoGo) is a precision metric tool designed for right-hand M4 x 0.5 threads. It targets the 6g tolerance class to help inspectors confirm the thread pitch diameter remains within acceptable limits, ensuring reliable fastener assemblies.

• Series: 686 Series ring gauges crafted for accurate, repeatable measurements.
• NoGo designation: Specifically built to reveal when threads are too large or out of tolerance by failing to pass through the gauge.
• Tolerance class: 6g metric tolerance, providing a defined standard for pitch diameter checks.
• Thread type: Right-hand M4 x 0.5 threads compatibility, aligned with common metric fasteners.
• Material and construction: High-quality materials designed for durability and long-lasting performance in shop environments.
• Measurement focus: Targets the thread pitch diameter to ensure only correctly sized fasteners proceed to assembly.

Using the NoGo gauge from the 686 Series, quality control teams can quickly determine if a fastener exceeds the maximum pitch diameter, preventing mismatches that could compromise strength and safety. Its precise, durable design supports repeated use across production runs, helping you maintain consistent thread quality and reduce rework. Ideal for machinists, inspectors, and manufacturing environments that require reliable, standards-aligned thread verification.
