The Craftsman set I bought 10 years ago when they were made in the USA has both 12 and 6 point sockets. 12 point sockets work on square nuts. Personally I prefer Kobalt over Craftsman now that they all make stuff in China. Both have the lifetime guarantee, but Lowes is a lot better at exchanging a broken tool than Sears.
Sears always beefs up the tool "count" with a bunch of allen wrenches and screw bits. Personally when I want a loose allen wrench I want it with the ball end and in a holder so I can find the one I want, not flat ends loose in a pouch.
