I picked up a six piece metric set of 3/8" drive Craftsman Industrial sockets back when they were on clearance at my local Sears Outlet Store. The set included 4mm, 5mm, 6mm, 7mm, 8mm and 10mm sizes. Although they seem to be well made in the USA, I haven't had a need to use any of them yet. The reason I brought them up however, was to say that I saw two metric sets in the same Sears Outlet Store approximately two weeks ago. So, they may still be around here and there.
Several years ago, I bought a six piece SAE set of 3/8" drive Craftsman sockets from my local Sears Store and I do use those frequently. The sockets were also made in the USA and included 5/32", 3/16", 7/32", 1/4", 5/16" and 3/8" sizes. I've been very satisfied with these sockets, and to be honest, I don't see any difference in the quality between the standard Craftsman sockets and the Craftsman Industrial sockets. That being said, you could probably just pick up a set of metric and SAE sockets at your local Sears Store. If the sets were made in the USA, you might get some good quality sockets at an unaffordable price.
