What tool can I use for large faucet lock nut

[sschoe2]

Hi my house came with this kitchen faucet that has always been loose. The nut underneath the sink is 2" or more and I haven't found a tool that can get purchase enough to tighten it. I tried a basin wrench, the Rigid type faucet install tool no go. There is also this gold looking thin nut I found underneath the sink that looks to be part of it. Can anyone please advise?

usually those nuts dont get tightened all the way it has 3 set screws that are tightened with screwdriver , nut driver , or socket wrench

some basin wrenches are made specifically for jumbo nuts.

That gold nut though doesn't look like it is designed to interact with the lock nut that is currently on there. I think there is usually a washer that goes between it and the gasket and the screws press up against the washer which presses against the gasket.

It looks like the locknut is a separate option or something. I just need to find a basin wrench that can get purchase on it? Something like this?

Maybe the nut you found in the cabinet was from a prior faucet. Or vice versa... but I would try it on the spout shank to see if it threads on. If so, you would also need a big thick washer to go atop of that nut for screws to push up against the sink that pushes the faucet down to tighten.

Otherwise if the nut that is installed is indeed the correct one, and you can back it off at all, I would lubricate the threads so when you do tighten it with an appropriate sized basin wrench, it will spin easier. Might make life easier if you cut away some of the 2x4 too.

Actually even if the nut you found will fit . you should be able to just tighten whats there and the other one just set aside

Mine does too but it doesn't get enough purchase on the nut to turn it. It slides on the teeth on the fixed part. The typical basin wrenches I see at the box store say up to 1.5" nuts.
