Hello,

I am trying to replace my kitchen. I have disconnected the water supply lines already but I cannot remove the bolt or nut that is keeping the old faucet in place.

The nut is very small and thin. I have tried using a basin wretch but the wretch is too big for it. I don't know how the socket wretch works or what size to use to remove the nut from the faucet.

You will have to determine the size of the socket to use on it by measuring the hex across flats. My best guess - 7/16 in. The proper socket will certainly remove the faucet - either by unscrewing the nut or unscrewing the mounting stud the nut threads on to or breaking that stud off.

A 7/16' deep socket on extended 3/8" drive should remove it. If it still refuses to budge, a Dremel will make pretty quick work of it.

There is probably a "plug" with a screwdriver slot inside the retainer. Remove it and the nut should usncrew easily. If it does not unscrew then you will have to force the nut loose with a deep socket.
