screw size - vintage 4001 "Grover" 4 mounting screws ?

[Sir Ricardo]

Greetings -

On a vintage 4001 that uses "wavy Grover" tuners, what size / type of screw is used to mount the tuner?

I'm looking at one right now; I've measured it as 7/16" long, and 1/16" wide. Pan head. Phillips. Chrome.

Does that sound about right? My measurements involved some serious squinting and guessing.

See photos.

What do you think? Any idea where I could get 30 or so?

thanks for any thoughts -

Richard
