ISO metric screw threads are the world-wide most commonly used type of general-purpose screw thread.

A wide range of GO / NO-GO fixed gauges are available for checking inside and outside threaded diameters, so as to ensure accuracy during the machining process. This ensures a “snug” fit between threaded components, which in turn phases out the loosening of screw-fastenend joints in your final work piece.
