ISO 7045 vs DIN 7985
DIN 7985 has a different head diameter in M3 and M5 and a different head height in some sizes. Many catalogues publish the DIN 7985 table under the ISO 7045 name. The sizes where the head changes have their own DIN 7985 files under the table.
The cross recess in the CAD files is a simplified shape for drawings and assemblies, sized by the recess diameter m. It is not the exact Phillips or Pozidriv geometry.
DIN 7985 pan head dimensions and recess size
At M4 the ISO 7045 head is up to 8 mm across and 3.1 mm high, with a size 2 cross recess, which is the screwdriver size. The recess number is in the table for every size.
