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.
