Odd sized Wright socket...

[RipD]

Got some new Wright 3/8 sockets. The 9mm is shorter than the others by about 4mm and is shorter than they specify on the web site. Seems odd. Possibly an older one? Mis-labeled shallow socket?

Not a big deal - just seems odd. Any ideas?

They make mistakes from time to time. I ordered some Wright hex bit sockets a while back and on a couple of them the socket was stamped one size and the hex bit was a different size.

I'm a Wright buyer since 1973 and yes, I have 3/8" drive sockets which are different in OAL than others in the same size. My guess is sometime in the past 40 plus years, Wright did some changes. Not sure why as it looks odd on a socket strip to have a odd duck which sticks up higher or sits lower than the normal progression.

I just noticed that the inside finish of the socket is different also. Not sure if it's intentionally unfinished or not. Socket on the left is the shorter 9mm. The 8mm is next to it. This kinda looks like a shallow socket to me. (Sorry - photo loaded upside down. Not sure how to fix that. It's oriented ok when I open it locally.)
