MS24593 is a flat head machine screw with a 6-32 shank/thread. In this
application the diameter of the screwhead is important.

I went to HD and bought a 6-32 machine screw to see what length I
needed (the original having rusted beyond recognition). I compared the
HD screw with the MS and noticed it was 1/4" dia. as compared to 3/8",
so I'm wondering if I order the MS screw if the head will be large
enough.

A 6-32 countersunk screw with a 3/8" diameter head? Even a 10-32 screw with
a 100° countersink will barely be 3/8".

If you meant 3/16", then the difference in the head diameter is due to the
87° or 90° countersink on the hardware store screw.
