Application Summary AI generated

This standard specifies the tolerance classes and limit deviations for miniature screw threads with nominal diameters typically below 1.4 mm. It is applied in precision engineering fields such as watchmaking, optical instruments, medical devices, and micro-electromechanical systems where small fasteners require controlled fit and interchangeability. The standard ensures consistent thread quality for assembly and performance testing of miniature threaded components.
