I own hundreds of Craftsman sockets. Metric and SAE, 1/4", 3/8", and 1/2" drives, standard length, deep well, 6 and 12 point, etc. I bought them 25 years ago. All made in the US. I think I purchased every type of socket Craftsman made at the time. They’re neatly arranged in three drawers.
About half a dozen sockets are missing. Lost for good. 
I want to replace them.
I went to the Sears website, but I didn’t see many individual sockets listed. I mostly saw socket sets.
It’s been forever since I’ve been to a Sears store. Not even sure if the ones near me are still open. Even if they are, do they sell individual Craftsman sockets?
