Removing Cartridge Nut

[Roback]

I had posted thread a week ago but not specific enough! Need help!
I have a single lever faucet with a cartridge retaining nut that measures 32mm (by caliper) from flat side to flat side. Measured gap from corners of nut to inside of the cartridge body which measures approx 5mm. I have tried two different 32mm and one 1.25 sockets which don't fit into the socket body. No SAE shower wrench socket works. Either too small or large. The cartridge nut sits just below the cartridge cavity, so I can't get to it with channel locks. I've already tried and rounded the nut slightly. Any advice would be very helpful. I found something that worked a few years ago but cannot remember what for the life if me. I am at a loss.

While you have your calipers, measure the ID of the cartridge body. How does that compare to the OD of the 32 mm sockets you tried?

Note that impact sockets are thicker than regular sockets.

From the picture: You will have to be extremely lucky to get any kind of a bite on this worn out nut.

What's the way out? Replace the faucet.

I think there is enough real estate to get a socket on it. Just need to find one that fits!

From your photo, I cannot imagine any socket that would fit the hex would be too thick to sit inside the recess.

You tried and rounded the nut to the point of no return.

Unless your picture is misleading, I don't think that a socket can get o grip strong enough to get going.
