I actually meant 'sockets with a hex bit in them', like these

since we're tlking about hex wrenches. (I have the sort you're
talking about, as well as a collection of wrenches. many sorts.)

the hex plus isn't hex shaped. it has the corners cut off (it's more
complicated than taht, but that's a first approximation), so that
the force is applied away from the cornders of the fastener hex.
That's not a bad idea, it's universal in box end wrench designs. I
haven't found it to be a problem with hex socket cap screws, though.
At least when using the right bit, because there isn't enough
clearance for the tool to rotate in the hole.


Right I agree. Much like SnapOn Flank Drive except inside out.
