Adafruit Terminal Block - 3-pin 3.5mm - pack of 5!

Nothing makes a project harder to maintain than a lot of loose wiring, which is why terminal blocks are essential for PCB-to-Wire connections. These 3.5mm terminal blocks are ideal: accommodating a range of wire gauges, easily adjustable with a screwdriver, and compact enough to maintain a tidy setup. However, they do not fit 2.5mm spaced holes, but can be used diagonally on most perf/proto-boards.

Designed with versatility in mind, these terminal blocks snap together so you can create an arbitrary length by connecting multiple 3-pin or 2-pin units. They are not compatible with solderless breadboards but are perfect for more permanent setups. Each purchase includes a pack of five 3-pin connectors.
