Hasselblad back screws

Hello guys, I recently received as a gift an A24 film back for my Hasselblad, while replacing the light seals I realized there was one of the 9 plate screws missing. Do you know where to get a replacement one? I'd prefer not to buy a broken back to cannibalize it, I'd rather buy the single screw.

Thanks in advance guys.

Try a hobby shop of the sort that sells RC planes and cars and model trains.
The ones here usually sell a variety of small screws.
