This is nothing new when you have one factory pumping out tools for several brands. In this case the SATA factory in China people's Republic of probably made this socket. They make Gearwrench, Husky, Duralast, and others. The same thing happened here when the Armstrong plant was open. you might get a NAPA socket mixed in with your Craftsman. I had a similar experience awhile back when I bought a 3 piece locking universal joint set from Capri. The 1/4 & 1/2 drive were stamped Capri but, the 3/8 was stamped MAC Tools

I don't really understand why CP the Tool Addict has gone off the deep end about this socket unless he's trying to agitate his base.

You have to remember that there isn't a Harbor Freight tool factory, a Capri Factory, a Matco tool factory or, many other fill in the brand name factory. There are tool factories that make tools for these brands though so, errors will happen from time to time. Move along, nothing to see here.
