I didn't see an image in your album that looked like the kind of thing I would normally refer to as a set screw. What exactly are you referring to? I believe this may be the relevant image.
That is the correct image. The screw connects to the wiper blade shaft.
So if I understand correctly, what you are looking for is that machine screw (a pan head machine screw). Assuming that the screw is stripped but that the internal threads of the shaft are still OK, that' should be a straightforward thing to do. Your goal is to determine three parameters - size (diameter) of the screw, thread count (threads per inch) and length. First, measure the diameter of the screw (or compare it to other machine screws of known size). Unless the manual wiper was made in Europe (which I doubt), the diameter will correspond to a number like 6,8, 10, 12 (I'd bet on 8 or 10 from the image). Most machine screws in 8 or 10 are either 24 threads per inch or 32 threads per inch and would be designated at 8-24, 8-32, 10-24, 10-32 etc. If the threads are not completely stripped, you can compare it to a thread gauge at the local hardware store. Once you know the size and thread parameters, all you need is the length and you can measure that with a ruler or other device. I find the local Ace hardware store to be the best supplier of stainless hardware but for more rare items, I order from McMaster Carr (they have an extensive catalog that is searchable on-line).
If you can't find the length you need, buy a slightly longer one and cut it down with a hacksaw. Prior to cutting it, put a stainless nut on it. Back that nut on and off a few times near the cut to help clean up the threads near where you cut. If you have a tap of the correct size, use that instead of the nut but a nut will work. After cutting taper the end a bit with a grinder and test the threads again with the nut. Everything should go on and off easily.
I'd also suggest that you replace the flat head pan screw with a Phillips head screw to make it easier for future removal and to less the chance of screwing up the head.
