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

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

I'm not smart enough to reinvent the wheel:

Can't access the end - tool slides along an axle. Can't drill a hole
crossways either (well you could but it wouldn't help any).



You could drill a hole, and use a pin spanner.
