Stronger tool and stronger grip.

A 6 point wrench has to be turned 60 degrees
between flats while a 12 point requires only
half that number. Thus the 12 point can be
used when there is less room to turn
the wrench.

Yes, this is the clearance/speed advantage that
has been touched upon.

A 6 point wrench (depending on tolerances)
bears on the entire length of the 6 flats on
a common bolt hear (or nut) while a 12 point
bears on a much smaller portion of the flats.

Right, but is it the flats that pulls the
nut/bolt head? Or the endpoints? But I suppose
the endpoints, on a 6, has longer flats.
(... did that last sentence make any
sense BTW?)

You can google on something like "Advantages
of 6 point wrench". You'll get about 480
thousand replies.

480 thousand plus one rather
