Provided it's the right thread and taper (60 degree for alloys usually) then it shouldn't make any difference, other than cosmetically of course, I may have some of the original flat ended hex ones somewhere, i replaced my old cars ones for ford ones with the big rotating collar on so I won't need them, I'll have a look tomorrow.
