- 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 mechanical properties of the screw are the same and meet the requirements of ISO 3506-1
- Depending on the length of the screw, these items are provided with a thread that comes near 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DIN 7991 has been withdrawn and replaced by ISO 10642. 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 steel models have been removed | property classes 10.9 and 12.9 have been added).
Due to their head geometry, these screws can only be subjected to limited loads; see DIN EN ISO 3506-1
