My $5 says it's not a 3mm screw.
Remove that screw and measure it.
More probably a ULS or a 7991 screw, m5x0.8 with a 3mm hex broach on the
head.
Agreed, although I'd bet more than $5.
It seems Tom doesn't know how to measure or specify a screw size.

Roger, do you have a caliper and know how to use it? If not exactly who
is convinced the world is flat? On my facebook page is a sampling og the bikes I've built from bare frames. How many have you? This is a tech
group and one wonders why you're here. You give no advice and apparently you're too smart to need any.
Cattrike is having trouble with his front derailleur. He says that he
knows how to install a fron derailleur. But he is having trouble what
would you suggest to him?

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?

I just measured one, but I'm a retrogrouch, Tom. I didn't
use a digital caliper. I used a Vernier caliper. (Do you
know how to read a Vernier scale? I'm betting on "no.")
I got 4.80 mm for the major diameter of the thread, or
0.192". Yes, threads are almost always a tiny fraction
smaller than their nominal diameter. Those screws are
absolutely not 4mm on any frame I've seen.
Again Frank cannot keep himself from speaking about what
he knowsz not.
Have you figured out how to post a link to a photo? Show us
a screw partially inserted in that mysterious threaded boss,
and show us how you're measuring its diameter.
BTW, besides working with various inductive proximity
sensors and other industrial sensors, besides working with
Labview data acquisition techniques, our students had to
learn to use various machinist's measuring tools - from gage
blocks to vernier calipers - in the Physical Measurements
course. As I've said before, Tom, you couldn't have made it
through the program.

0I know of one exception in all those. One. It was a
bright yellow Galmozzi owned by Andy Hampsten when he was
a promising teenage amatuer. Galmozzi had brazed 5mm
screws sticking up off the downtube (frames had one mount
or none in those days). The bottle secured with nuts.
But not 4mm.
As an aside, ISTM that m5x.8 od the most common SI size I
come across for general use screws. For the U.S., it seems
1/4-20 is the most common. I have no data, just my general
impression - maybe because most metric stuff I use is bike
related?
Bit if true, I wonder why the difference in diameter. m6x1
is much, much closer in size to 1/4-20.

Wrong (as usual).
The head diameter is always larger than the major diameter across the threads. The metric screw size is major diameter. <https://www.afi.cc/customer/asfain/Hubspot%20Files/Hubspot%20Site/Files%20Uploaded%20from%20Hubspot/Screw%20thread-1.jpg>
For example, a 5mm screw would measure 5mm across the threads.

No matter how many frames you have, the bottle mounts are all m5x0.8.

Not really smart. It was an impulse buy at a local thrift store. It
looked new and the price was right (about $10). I don't really need
it as I have other calipers and micrometers: <https://photos.app.goo.gl/G2Tseb249vH8zSi27>

Nice. However, I don't need such hardware very often. Instead, I
just drive to the local hardware store and buy as needed: <https://www.scarboroughlumber.com>
They don't have everything, but between their inventory and my
disorganized collection of fasteners that I've accumulated over the
year, the arrangement works well. If I need to order fasteners on
eBay, I usually order 100 at a time. <https://www.ebay.com/sch/i.html?_nkw=m5%20set%20screwup%20stainless%20assortment>

It's not uncommon for people that are not mechanically
inclined to confuse an Allen bolt's threading with the Allen
wrench used on the head.
Here is a chart to help him understand: <https://

It's possible that there are specialized M5 Allen head bolts
that don't use a 4mm Allen key but personally I've never
seen one since there would be no point in it.
