Review on Black Mounting Nuts PK2, American Standard 065800-0070A by Tony Wilson

One side of the faucet in my child's room is a bit loose. I reached under the sink to tighten the mounting nut and it broke in my hand. I looked for a replacement at two large stores (one orange, one blue) and a small hardware store chain. Nobody brought anything like this. It's strange not to carry such a simple repair part with you. Anyway, found this on Revain. Arrived on time and problem solved. I have a Glacier Bay faucet. I assume they will fit any bathroom faucet with a 3/4 inch connection.
