Introducing the Asimeto Ring Thread Gauge (NoGo) — a precision metric gauge built for quality control and manufacturing teams working with metric fasteners. With a 6g tolerance rating and a NoGo designation, it confirms whether M5 x 0.5 threads stay within the accepted pitch-diameter limits, helping ensure reliable, safe connections in every assembly.

  • 6g tolerance class: designed to match the 6g specification for accurate pitch-diameter measurement on M5 x 0.5 threads.
  • NoGo designation: test that identifies oversize or out-of-tolerance threads; if the fastener cannot pass through, it exceeds the maximum allowable pitch diameter.
  • Metric right-hand thread: specifically engineered for standard M5 x 0.5 measurements in metric systems.
  • 686 Series construction: crafted for precision and durability, using high-quality materials to withstand regular use in workshop environments.
  • Designed for quality control: ideal for inspection in manufacturing, maintenance, and supplier audits where thread integrity matters.

By incorporating this gauge into your workflow, you can quickly validate thread fit before assembly, reduce the risk of cross-threading or stripping, and maintain consistent interchangeability across parts. It supports faster checks on production lines, repair benches, and field service where reliable fastener performance is critical.
