For N type MB part numbers the DIN # is found in the first six digits omitting leading zeroes.
So the MB part number N007987008119 is a DIN 7987 screw. That DIN number now is replaced by a DIN 965 screw which is a flat head countersunk machine screw. Not always clear to me how to read the diameter and length from the last digits , but I am sure someone can explain that.
Mercedes has issued some useful DIN catalogs showing the different types of screws, fasteners etc. that correspond to the various DIN numbers.
