No no no. That's for pin lock kegs. We don't have those.
I believe you need a 22 mm deep well socket. I see places online talk about 7/8" but I remember that being sloppy which can strip the edges, and when I replaced it with metric I got a perfect fit.
Also if we have a set of metric box wrenches, you could try one of those first, but I find a deep well socket to be more convenient.
