Arduino Proto Screw Shield

Used stranded 16 AWG wire for a servo project and the 3.5mm pitch terminals held it firmly without any solder. This is way more solid than standard pin headers.

The screw terminals are a perfect size for the thicker sensor wires I use, and they grip firmly without any stripping. It took me about ten minutes to solder the headers on, but now my connections actually stay put.

Finally stopped fighting with those flimsy pin headers — the screw terminals grab solidly and my wiring actually stays put now. Took me ten minutes to move a whole breadboard project over, and the 3.5mm pitch works perfectly with the thicker cables I had lying around.
