- Due to their head geometry, countersunk head screws have a limited load capacity according to this standard and possibly do not meet tensile or torsional strength requirements.
- The actual mechanical properties of the screw are unchanged and comply with ISO 3506-1
- Depending on the type, these items are supplied with threading almost up to the head
- Countersinks for screw heads in accordance with DIN 7991 and ISO 10642 must comply with DIN 74 shape F
DIN 7991 has been withdrawn and replaced by ISO 10642. There is some limited similarity (some head heights and head diameters changed | Nominal diameters M18, M22, M24 removed | Strength classes 10.9 and 12.9 added).
These screws can only be subjected to limited loads due to their head geometry, see DIN EN ISO 3506-1
