The Asimeto Ring Thread Gauge (NoGo) is a precision metric gauge designed for quality control of external threads. Built for machinists, inspectors, and manufacturing shops, it ensures M20 x 2 right-hand fasteners meet the ISO metric 6g pitch-diameter tolerance.

• Series: 686 Series ring gauge engineered for sturdy, repeatable measurements in daily use.
• Thread Size: Metric size M20 x 2 with right-hand thread to match standard fasteners.
• Tolerance Class: 6g external pitch-diameter tolerance, providing a reliable mid-range fit for metric threads.
• NoGo Designation: Specifically specified as a NoGo gauge to identify threads that are too large or out of tolerance.
• Application Type: Used as a Go/No-Go check to confirm parts either pass (Good) or fail (Too Large) against the limit.
• Orientation: Right-hand threading orientation aligned with common fastener configurations.
• Durability: Crafted with precision machining and high-quality materials to endure routine gauge checks.
• Identification Mark: Red indexing mark aids quick recognition of the NoGo end for fast inspection.

This gauge helps prevent oversized pitch diameters from entering your assemblies, reducing the risk of cross-threading and joint failure. Use it in production lines, QC labs, or maintenance workshops to streamline inspections: the part should pass through the Go side and fail or resist on the NoGo side if out of tolerance. The 686 Series design supports consistent, long-term accuracy, so you can rely on repeatable measurements across shifts and operators.
