Mark, There are many different styles of screws that you could choose from. There are slotted pan head, phillips pan head, Allen head, hex head, and others.
By 3 mm I believe you mean M3. You also need to specify the screw thread pitch, the standard being M3 x 0.5 mm. In addition to the pitch, you need also to specify the length. If you live in the US, then try a local hardware store or DIY store. If they don't have the right combination of diameter and length then try a company like McMaster-Carr.

I want to install it in a wooden tea box for resonance. I went to Motion Industries in Lancaster, CA and asked them. They referred me to Fastenal, who did not have that small screws, but the man was helpful and had a thread gauge that appears to be 3mm (measuring the ID's). He suggested that I could go to a hobby shop. I am going to San Fernando Valley today, hoping I can find the place to buy three screws. Would anybody have any suggestions where I can find them?
