Ferrule Connector Kit

It turns the loose strands of a stranded wire into one solid pin. That stops the strands splaying or breaking off when you tighten a screw terminal down on them.

1.5 mm² to 6 mm², which is roughly 16 to 10 AWG. Each size has its own colour so you can pick one by sight.

The screw crushes some strands and misses others, so the contact area is uneven and the joint tends to loosen over time. A ferrule spreads the clamping force across every strand.

Yes — a crimping tool sized for ferrules. Strip the wire, slide it into the collar until the strands reach the end, and crimp.

Each one has a colour-coded plastic collar. It insulates the back of the ferrule and guides the strands in cleanly as you insert the wire.

Anywhere stranded wire meets a screw terminal — control panels, terminal blocks, breakers, inverters and battery boxes, in vehicles, boats and industrial equipment.

They are made from corrosion-resistant material and the crimped pin does not move inside the terminal, which is what keeps the connection stable where things vibrate.
