RCPROPLUS S6 Solder-less Connector 6mm For Battery (8M-8F) (8AWG)

I like these(not as much as the all one color), but the set screws are longer.. They're great for smaller ga wire, like 10, but for 8, I find, I have to file the screw ends down, to clear the connector case..

My favorite connector, Best size for money.

Terrific connectors that work as designed. Only suggestion is to crimp a ferrule to the wires before tightening to ensure a positive connection and minimize chances of wires coming loose.

A great idea, solderless connectors. Here's where they need improving.
They need to provide more set screws. Each terminal has 2 threaded holes, so both set screws compress the wire from both sides, with only 1 screw it pushes the soft braided wire out of the way even if you fold it to double its' diameter. Now go order additional set screws! Ok, 1.5 mm driver what's the thread? Common guys, for that $ you couldn't supply enough?

Excellent connectors! HD always has the best prices and fast shipping!

Forget soldering connectors. This takes the worry of a cold solder out of the equation.
