4-40 means a size 4 screw with 40 threads per inch, 6-32 is a size 6 with 32
threads per inch etc. Can't tell you where the size 4 and 6 come from
though. Unlike wire and sheet metal, the larger the number, the larger the
size.

Good thing these sizes aren't like women's clothes otherwise nothing would 
ever fit.
