The Asimeto Ring Thread Gauge (NoGo) is a precision metric tool designed to verify the maximum thread pitch diameter for M25 x 1.5 right-hand threads. Built for machinists, quality-control technicians, and fastener manufacturers, it delivers quick, reliable pass/fail checks to ensure correctly sized fasteners are used in assemblies.

• 6g tolerance class: Specifically ground to the 6g specification, ensuring accurate measurement of the thread pitch diameter for metric threads.
• NoGo designation: Used to determine if threads are oversized by testing whether a fastener can pass through the gauge; a failure indicates the pitch diameter is outside tolerance.
• Thread format: Metric M25 x 1.5, right-hand thread, matching common industrial fasteners.
• Series and build: 686 Series gauge crafted with precision and durability in mind.
• Construction: High-quality materials and a knurled outer edge for secure handling and repeated use on the shop floor.

With the Asimeto NoGo gauge, you gain fast, decisive verification that fasteners fit within spec, reducing the risk of assembly issues caused by oversized threads. The tool’s durable build supports heavy use in workshops, toolrooms, and QC stations, enabling consistent measurements and confidence in every fastening operation. By clearly signaling out-of-tolerance parts, it streamlines quality control and helps maintain reliable, safe connections across manufacturing workflows.
