This International Standard specifies the profiles, diameter-pitch combinations, basic dimensions, tolerances, limits of size and designation for ISO miniature screw threads with nominal diameters from 0,3mm to 1,4mm. These threads are applicable to timepieces, optical instruments, electrical meters, measuring instruments, etc.
The profiles and tolerance system for ISO miniature screw threads (S) differ from the profile and tolerance system for ISO general purpose metric screw threads (M).
For threads with nominal diameters from 1mm to 1,4mm, designers shall decide to use ISO general purpose metric screw threads (M) or ISO miniature screw threads (S). ISO miniature screw threads are shown in AnnexA.
AnnexC illustrates the differences in miniature screw threads between the ISO International Standards and those of certain countries.
