Went to habitat for humanity today, found a nice tool box. But they also had these 12 pt sockets from japan the looked like they were 13 mm allen drive. I didn't buy them though. Any info about them?
I didn't get any pictures of the sockets, but I found a picture of a set. These were made by None Better tool co. I guess each set included an allen wrench to turn them. There was a stamping on each socket that looked like the word Japan that was worn down. They did have knurling & were very shallow. I might go back for them.
