Recently I replaced a faucet in the kitchen, but there is not enough room to fasten two nuts. These are not the nuts on the end of the supply lines; they thread onto studs to hold the faucet down. They're too close to the supply lines to be able to grab.
I tried with a wrench and a rib joint pliers, unsuccessfully.
How can I fasten nuts without calling a plumber? Is there a specific tool to achieve this or something else?
UPDATE:
I added some pictures to explain my case better.
Pic #1: These are the nuts. At the moment, they have been tightened just by hand:
Pic #2: As I said before, there is really not so much room to tighten due to sinks and pipes. As for pipes, they are almost attached to the nuts, hence a basin wrench is not the best option, in my opinion:
Pic #3: This is a detail from the faucet assembly instructions that shows a better perspective.

What you're after is a tool called a basin wrench:
It can reach up behind the sink and tighten those nuts.
