Default filing flats on a socket

I'm making a special tool out of a 3/8 drive socket. It'll have to be
turned by a wrench or gripped by vise jaws. I'll file flats on the
square end.

Should the flats be parallel with the square's sides, or have the point
in the middle? This is a high-torque situation.


I have no scientific answer or explanation, but my gut feeling
suggests parallel.

BTW: Those sockets are really hard. Filing might be near impossible.
In a similar application, I used an angle grinder.
