2Set Brass Faucet Lock Nut Secure Faucet, for 32mm Outer Diameter Water Pipe, Installation Kit of Bathroom (Lock Nuts Inner Diameter:32mm/1.23in)

Plumbers told me to buy a new faucet when all I needed was this piece!

I looked high and low for this part locally, even online it was hard to find. I'm happy I found it here. I didn't realize at the time I was getting TWO! That was a surprise bonus. I currently dont need the second, but it will come in handy some day. So in my mind, I got a 2fer...lol. The nut went on smooth, threaded well. Appears and feels solid. Will update here if that changes.
