Bouchon Williamsburg 918428-0070A

Exactly as pictured. Good quality, served the intended purpose. It's a screw and it screwed.

This screw seems to match exactly the original screw that I thought I had lost. I'm holding on to it since in my collection of Williamsburg faucet parts I have one screw I had to drill out to remove and one that sheared off. Never know when a new one will be needed.
