Square heads are eight or four point:)
Six point sockets don't slip as easily as 12, and there are 12 point bolts.
Mostly you use 12 point sockets on regular hex bolts and nuts with no
problems. Some 12 point sockets like Utica Loc-Rite's and others use rounded
points to make them harder to slip.
The 6 point are for people with a lower IQ than the 12. <lol>
Seriously, 6 point ones hold better, but you have to rotate them more
to get them on, and in tight spots the 12s work better. A 6 is much
less likely to strip the head on a bolt too. Those are the reasons I
know, there may be others too. I like having both.

And with big bolts, even a 12 isn't going to strip the head unless it
is tighter than anything I've had. With little bolts, even a girl
could strip the head with a 12, but not with a 6.
With a 6, one might "super-torque" the whole head off, but at least he
won't ruin the head.
Also some bolts actually have 12 point heads, like certain ARP engine
fasteners. I prefer using 6 points for general work, but there is a
definite place for 12 points in my toolbox.
replace "roosters" with "cox" to reply.
