You'd think, but it doesn't work that way. The socket attaches to the
breaker bar with a square fitting. That gives you additional angles.
Considering a 6 point socket, the sides represent a 60 degrees change,
as you say, but you can also move the breaker in the socket, with is a
90 degree change. The result of doing both is a 30 degree change, same
as a 12 point.

For high torque fittings, a 6 point is definitely called for (unless
the fastener itself is 12 point, as some newer VW axle nuts are).
