Rear dropout adjustment screws?
I went to do a search, and frankly, I was at a loss of what to search for.
Here's the situation.
I have a properly dished rear wheel on an older mid '90's vintage steel bianchi. I noticed that it doesn't line up straight in the dropouts. This is likely the cause of some drag and pulling that I found the last time I had it out. There are holes drilled and tapped in the rear dropout for those little adjustment screws that are used to center the rear hub. However, no screws.
Where can I find some? Alternatively, if someone knows the size and thread pitch I might be able to find them at a hardware store, although I'm not hopeful as they are likely metric and an odd size.
I stopped by one of the local shops and they didn't have any, nor know what the size/pitch is.
Thanks for any help!

They are 3mm screws. 1.25 pitch, if I am not mistaken.

They aren't really needed. They make for quicker wheel-changes on bikes with horizontal dropouts (please refer to Rae Dong Chong's 4-sec rear-wheel change in that movie). But once you have the QR tightened, the position of the hub & wheel should be fixed. If your wheel ends up moving and the tyre rubs on a chainstay, the problem is with the QR or dropout-face, not the missing screws

yeah, they don't really do anything once the QR is tightened.
your rear wheel is pulled forward when the QR slips, so all they really do is help you line up the wheel to where you want it before tightening the QR.

Yeah, I know they aren't really needed. That's irrelevant...hehe.
