The Asimeto Ring Thread Gauge (NoGo) from the 686 Series is a precision tool for machinists, inspectors, and assembly professionals who need reliable metric thread verification. Designed for M42 x 1 right-hand threads with a 6g tolerance, it provides a clear NoGo pass/fail check to confirm the pitch diameter stays within spec.

• Designation: NoGo gauge for quick identification of oversized or out-of-tolerance threads.
• Thread size: Metric M42 x 1, right-hand thread specification.
• Tolerance class: 6g, ensuring tight, repeatable pitch-diameter verification.
• Series: 686 Series, built for precision and durable performance.
• Construction: Crafted from high-quality materials with a knurled outer edge for secure handling and repeated measurements.

This gauge streamlines quality control and on-the-floor checks by delivering a straightforward, objective assessment of threaded fasteners. Use it to prevent mismatches, reduce rework, and ensure reliable, safe connections in mechanical assemblies that rely on precise M42 x 1 threading.
