You can get set/inset/grub screws from machine screw specialist shops, there are a few at the ubi area (if you drive), if not your best bet is to go to the Jalan Besar area behind hackerpace (Kallang MRT is nearer) and ask around the shops there.
Or if it's a common small size you can try r/c shops, or I might have a spare. Could you please measure it with a micrometer and tell me the diameter + length?
