Asimeto Ring Gauges
NOGO - Metric Fine 6g - 686 Series
These ring gauges are specifically designed to meet the 6g tolerance class, ensuring precise measurements of the thread pitch diameter. With their NOGO designation, these ring gauges determine whether the threads are too large or out of tolerance. When a fastener fails to pass through the NOGO ring gauge, it indicates that the thread pitch diameter exceeds the maximum acceptable limit. This helps ensure that only properly sized fasteners are used, promoting safe and reliable connections. The 686 Series ring gauges are crafted with precision and accuracy in mind, using high-quality materials to ensure durability and long-lasting performance.
