Here's an interesting socket, double ended 13/16" and 7/8", also labeled 21mm and 23mm. I assume the ratchet would require an extension to actually attach to the 1/2" drive ratchet.
Update, after reading the comments I remembered I had picked up an odd bent "extension" some time ago, and it would be for this very socket. (Bottom)
Sockets like this are called Budd sockets
ReplyDeleteA flip socket for use with a Gorilla-style breaker bar like this, so no extension or ratchet necessary:

These are often sold with a bar for wheelnuts. D.
ReplyDeleteThanks guys, I just remembered I had found a mystery something a year ago that is exactly what you are describing. (post updated)
