Washer would not fit
The washer for the mounting nut that came in the box with the faucet, would not fit. It is "too narrow". One side would line up but the other side was short of lining up. Since I couldn't install it, I didn't. There are no leaks!!! Do I need to???
Thank you for your question, Lisa. The washer provides a solid surface for the jack screws and protects the underside of your sink or countertop from getting damaged by the screws. Installing the faucet without the washer is not recommended, but will not cause a leak.

Is there an alternate nut available for the Trinsic 9159?
The countertop installers drilled the faucet hole to close to the under mount sink, and the Delta Trinsic mounting nut with screws cannot be used. Is there a standard round or hex nut available for this faucet?
Thank you for your question. Unfortunately, we do not have another mounting nut available for this faucet.
Depending on the installation, it may help to use an RP37490 as a spacer, which can be cut to fit your installation. The mounting nut and washer would still need to be used.

What is the thread size if this nut? I have a very tight situation and the one that comes with it is just both too big and too difficult to grip to get it fully tight. I need to replace with a more standard size bolt, but need to know the size and threading.
Thank you for your question. The thread size of the nut for the RP49835 is 1.25-20 UN-2B.

Loosen Mounting nut???
How do you remove the mounting nut? I read the answer from an earlier thread and it's not helpful to a non-expert. It's an awkward shape to get a wrench on it and how does leaving the screws in help me loosen it?
Thank you. Jeff
Thank you for your question. Once you loosen the screws, they should stick out below the nut enough for you to turn it using your thumb and forefinger on the screws, as you would with a wing nut.

What is the diameter of the large flat washer?
I have a close clearance situation between the undermont solid surface sink flange and the back of the cabinet.
Hi Pete, Thank you for your question. The washer in RP49835 has a 2" diameter.

How do I remove the mounting nut?
I am attempting to remove my 16928-SSSD-DST. The mounting nut is listed in the installation instructions is RP49835. However, mine has black plastic surrounding the actual nut.
How is this part to be removed? The screws have been removed, but I can't get a grip on the black plastic to remove the mounting nut. It looks like the plastic is formed to accept a specialized tool, but I can't find any information on it.
Hi KT, Thank you for your question. You will want to loosen, but not remove the screws from the RP49835 and then use the screws to unscrew the mounting nut. We do not offer a tool to remove this assembly.
