Technical specifications
| DIN 7991 has been replaced by ISO 10642. They have limited interchangeability. Some head heights and head diameters have been changed. Nominal diameters M18-M22-M24 have been omitted. Stainless steel was removed and the hardness class for steel 10.9 and 12.9 added. The notation "08.8" and "010.9" indicates that these screws may only be subjected to limited loads according to DIN EN ISO 898-1 due to their head geometry. |
