Maybe a "metric" 13/16" sparkplug socket. Perhaps made for a sale outside of the U.S.

Just a guess.

yeah what you get when you need a 13/16 in a metric system.

There is also a 5.5mm socket, which is not a US equivalent.

Thanks. Interesting. I couldn't find that part number or socket on the snapon site. Google yields some additional computer related stuff. The conversion comes out to 20.64mm--0.8125in--13/16
