Screw Machine Pin have very small tolerance, can't fit in BIG FAT pins like the ZIF socket has.

Stamping Pin can expand more so FAT pin's can be forced in, not a good practice to remove it to often anyway, once you got it in keep it there unless you must remove it.
My ZIF socket fits fine into the receptacles of a machine pin DIP socket. The trick was to remove the cross connecting links to give two, single row, machine pin carriers. I have been using it like that for a couple of years in my proto boards.
