I have a reverse osmosis kit, and the faucet has a really long bolt which you use to attach it to your countertop. I can't get a tool up there to tighten it because the sink basin is in the way. I wonder if there is something like a sleeve I can put over the bolt so that the tightening nut sits much lower. Then I can get at it more easily with a tool. Does this thing have a name?
Thanks
Based on the clarifications, I would recommend using a reusable thread-locking liquid.
Here is a link to one I found that may work. I have not used it.

Lock nuts and carriage bolts are a bad combination and even worse when trying to use them in material like particle board or MDF.
You could try to use a Tee nut from the monitor side and then simply use a short hex head bolt into the Tee nut.

It's called a "bushing", "sleeve bushing", or "sleeve bearing". They're commonly available at hardware stores in brass, bronze, aluminum, plastic (nylon), and steel, and they can be stacked or cut to achieve a custom length.
