[Milsurplus] [ARC5] Source for #2-64 cheesehead screws?

[hwhall at compuserve.com]

Thanks for all the suggestions so far, though the closest is a standard fillister head which isn't wide enough. From the specs accompanying fillister screws, the standard fillister head appears to be 1.6 times as wide as the major 2-64 thread diameter.  The screw I need to replace has a head that is 2.5 times the thread diameter. 

A pan head is nearer the right relative size, at 2.1 times the thread diameter. If I go up to a screw size with a suitable head dia though, it looks like I'm at a thread dia that I can't get into the 2-64 die to try to rethread it. Maybe what I need is a micro machinist?
