ISO 10642 replaces DIN 7991 | There are some limited consistencies (some screw head heights and diameters have been amended | the M18, M22, and M24 nominal diameters have been removed | stainless steels have been removed | strength classes 10.9 and 12.9 have been added).
Due to the geometry of their head, the screws have a reduced load; for more details, see DIN EN ISO 898-1
