Remember when I said that my bike had 4 mm screws for the water bottle mount? Flunky told you all that I was lying because 5 mm was the standard for all water bottle mounts. Funny thing is that my new Time ULTeam uses 3 mm with a wide head. Perhaps Flunky can suggest why the country of the Tour de France doesn't stick to his "standard"?

Remove that screw and measure it.

Part true, The 4 mm head was on a 4 mm screw and the 3 mm head is on a 4 mm screw. Were you correct wouldn't that mean that a 5 mm head would be on a 6 mm screw?

In the old days, I'd have told you "Take out your copy of _Machinery's Handbook_ and look it up." But these days you can find that information online. See "drive size" at https://tinyurl.com/t3xh9wk6
Or hell, just measure one.
If you think it takes a 4mm screw to fit any normal water bottle mounting point, you don't know how to measure a screw.
