ISO 7046 vs DIN 965
The DIN 965 head is different in most sizes, and many catalogues list the DIN table under the ISO name. At M4 the ISO head is up to 8.4 mm across and the DIN head 7.5 mm. The DIN 965 sizes have their own 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 965 countersunk screw length
The head is a 90° cone and the length includes it, because it ends flush with the surface. The recess number in the table is the screwdriver size, 2 at M4.
