Universal PCB Screw Terminal Blocks Connector - 5mm Pitch
Now available from PMD Way are popular screw terminals with 5mm pitch pins. Available in 2 or 3 positions and in either green or blue.
They have the really cool feature of slide-locking together to form any size you need (4, 5, up to 20 without problems).
Rated for up to 300V @ 8A. Terminal can accept 26 to 14AWG wire. 5mm/197mil pin pitch will line up well with standard 0.1" perf boards but the pins are thick enough (1.0mm OD) that you may need to increase the hole diameter on some perf boards.
Sold in packs of 100.
