 I'm designing a relay module, with some number of independent SPST
power relays, and I thought it would be convenient for the customers,
if any, to be able to buss one side of some of the relays sometimes.
But without soldering.
 If we had a row of holes on the board, one could bolt down strips of
buss bar as needed. So I want to buy a flat metal strip with evenly
spaced holes. A customer could, say, snip off a bit with 5 holes and
bolt it down with 5 tiny screws to cluster 5 channels.
 Searching for  buss bar  gets thousands of silly hits.
 I recall companies that made this sort of thing, electronic pcb bus
bars, standard and custom. Does anyone know of any?
 Back in the DIP ics and double-sided board days, we'd sometimes use
soldered-down bus bars for power and ground distribution.Maybe some
people still do.
 

You can also use seperated screw terminals:
