The Asimeto Ring Thread Gauge (NoGo) is a precision metric gauge designed for quality control teams, machinists, and assembly technicians who need reliable internal thread verification. It targets M38 x 2 right-hand threads and helps ensure every threaded connection meets exact pitch-diameter standards.

• Series: 686 Series ring gauges built for precise internal thread inspection
• Thread size: M38 x 2, right-hand thread for metric applications
• Tolerance class: 6g, enabling strict pitch-diameter control
• NOGO designation: quickly identifies threads that are out of tolerance by preventing a through-pass
• Material & finish: high-quality, durable metal designed for long-term shop use
• Design purpose: specifically for internal thread verification to ensure correct mating with fasteners

This gauge provides a clear pass/fail result: if a fastener cannot pass through the NOGO ring gauge, the internal thread pitch diameter exceeds the maximum allowable limit. Using the 686 Series gauge helps you detect oversized or out-of-tolerance threads early, reducing rework, scrap, and assembly delays while protecting the reliability of critical threaded connections in manufacturing, maintenance, and repair environments.
