Most (like 90%) of my sockets are Snap On six point
I have a twelve point set of shallows for doing 12 point bolts
I also have a few 1/2" drive 12 point sockets for torquing ARP rod and head bolts when I use them
My Snap On 3/4 drive set is all 12 point, Kinda bugs me but I've never had it round anything off
Plus, lots of the newer diesels, Cats and such use 12 point head bolts
