I am not familiar with this bronze colored nut that is holding my current Grohë Ladylux kitchen faucet to the counter. Does anyone know the best way to remove this? Thanks very much in advance!
EDIT: I figured it out. You CANT unscrew the bronze colored piece from below. You have to Disassemble the upper part and then there's an internal threaded bit in the upper part that you have to unscrew. The guy in the video whips out some special tool that hasn't been seen or mentioned before in the video and uses it to unscrew the interior threads. I don't have that magical tool, so I just used pliers. https://www.youtube.com/watch?v=HRZ1QOinJsE
Like others have said, usually there's a bolt on the underside, but I have trouble seeing it in this picture. In some faucets (also some Grohe) there's an Allen inside the faucet. Remove the spout by loosening the ring around the spout and there should be a threaded rod in which fits an Allen key.
