Dirt, actually. I think these are going into the "free" pile for the next YS.Yeah they have been Chinese for awhile. Moved from USA to Taiwan and then China. Doesn’t look like there is much QC with those rusted ones.
Seeing as there's a 14mm in the bunch, and no 16mm, I'd be more expecting to see a 5/8" if that (cognates) were the reason.For many purposes, 14 MM and 9/16 wrenches are interchangeable.
Stanley made in USA but not sockets. Friday I ordered metric socket head cap screws from McMaster-Carr, delivered yesterday. Opened the package, green box, assumed Hillman but it wasn't. Looked at the manufacturer and COO, it was Stanley made in USA, was very suprised.
