I have a canopus firewire ADVC 100, it's just a white plastic case with a
circuit board in it. The case is held together by four small self tap screws
and I'm having difficulty properly identifying what they are because I want
to buy some more of these but longer. If I put the screw in a micrometer the
diameter of the shank is 2.6mm and the screw itself is about 10mm deep,
overall including the head it's 11mm long. How do I locate the correct
name/ID number of this screw? I would like to buy some 15mm or 20mm versions
of it. I've looked on google but haven't been able to ID it.
