Application Summary AI generated

This standard specifies the series and basic dimensions for metric screw threads with extra fine pitch, providing a unified technical reference for thread design. It is applied in precision mechanical systems, such as aerospace, automotive, and instrument manufacturing, where fine adjustments or high-strength fastening under vibration are required. The standard ensures interchangeability and compatibility of threaded components in contexts demanding tighter tolerances than standard fine threads.
