Precision meets reliability with the Asimeto Ring Thread Gauge (NoGo) for metric threads. Designed for machinists, quality teams, and manufacturers, it verifies M40 x 1.5 right-hand threads to ensure fasteners meet the 6g tolerance class and pass essential quality checks.

• Gauge Series: 686 Series precision ring gauge built for durable, repeatable measurements.
• Thread specification: Metric M40 x 1.5, right-hand threading aligned to standard fastener sizes.
• Tolerance class: 6g accuracy for precise pitch diameter measurement.
• NOGO designation: Determines if the thread is too large or out of tolerance—quick pass/fail assessment.
• Construction: High-quality materials and precision finishing designed for long-lasting performance.
• Handling: Knurled outer edge for secure grip in busy shop environments.

Using the NoGo gauge provides fast, reliable confirmation that a fastener's pitch diameter does not exceed the maximum limit, reducing installation issues and rework. The 686 Series design ensures consistency across lots, supporting stringent QA in tool rooms and production lines. By catching oversized threads before assembly, you improve the safety and reliability of joints and streamline quality processes with clear Go/NoGo results.
