All except the first sentence, I knew the link's complete description before I posted above.
I explained in my post above that the link's description is a good match for our 425380 hex bolt but since the rest of the original
7372885 screw, int-teeth-lock washer, hex-hd, S, cd or zn-pltd, 1/4-20NC x 5/8 (superseded by BOLT, H101-0425380)
which normally is the description of a hex head bolt with a common slot or phillip's head drive.
Since none of us appears to have a guaranteed original 7372885 screw we cannot be sure what the original screw looked like.
I did survey all the illustrations in TM 9-804 dated Sep 1950 and most of your list of original 7372885 screws did not show any screw driver common slots or phillip's drive indents. So it is quite possible the screw in the link may be useable for the 2372885 screws as well.
