The term is "via".

If you are looking for the name of the parts used to make vias on homemade 
PCBs, I can think of two: Harwin "track pins" and Multicore 
"copperset".  Track pins are a tapered pin that fits tightly into a #66 
drill hole - you solder both top and bottom sides to make the 
connection.  Copperset vias are used to make real vias on a PCB - you wind 
up with a plated through hole.  But they are expensive and time consuming 
to use.
