What Does This Brake Lever Screw Do?
This is a Yake mechanical disk brake. It looks like the screws were installed backwards. Now the one on the left has fallen out somewhere. Do they have something to do with setting the brake engagement point? If this is how the screw is supposed to be installed, how can you adjust it with the head inside the lever?

Look closer and you'll likely see that it takes an Allen (hex) wrench

It may be slotted for a small flat head screwdriver. Screwing it in will cause the lever to be closer to the bars for smaller hands.

Do you need the brake lever closer to the handlebar? If not, you don't need the screw. If you do, unscrew the one in the other lever, take it to your local hardware store, and see if you can find one to match (it's a metric size, probably). A local bike shop might also have a couple in an old parts drawer somewhere.

I think on a set screw type the wrench size matches the thread size???

Look for an actual "threaded fastener" store in your locale.
I'd guess that size is between 2 & 3mm.
IF you don't mind a screw head on the end, you could use a "standard" Metric screw in a pinch.
You may simply not need it for you?

Those screws are the same as pegs on pedals. Mostly they just wiggle loose and disappear.

The 2.5mm hex is a common tool for bikes, I've used it for brake spring adjusts, grip shifters, and bar end mirrors.
For those anti-Park tool, the 2.5mm can often be found in big box stores in folding toolsets.

Now that I know how that screw works, I've been experimenting and I do like the brake lever having a smaller reach (I have relatively small hands). I don't know why I was thinking I needed to find an identical screw, a standard hex bolt of the same size should work. Thanks!
