Notice

DIN 7991 has been withdrawn and replaced by ISO 10642. There is some limited similarity (some head heights and head diameters changed | nominal Ø M18, M22, M24 removed | Stainless steels removed | strength classes 10.9 and 12.9 added).



Due to their head geometry, these screws can only be subjected to limited loads, see DIN EN ISO 898-1
