This is simply the best kind of wirenut. It has a huge range of wire sizes and quantities it will grip. It goes on easily, holds on well, and doesn't waste a lot of space with stupid giant wings.

Best wire nuts. They really hold on to the wires. Have not had a single one fail.

I have cloth wires, knob and tube, as well as new construction. These 3M connectors have not loosened over time, and have created much safer connections in old outlets and ceiling junctions. I don't know if there is a difference between brands, but these have never failed me or come loose.

We rely on these heavily in our HVAC business. They grip and never *slip. Less loose connection calls means we save money in the long run with less inconvenience for our clients.

It is really hard to find something to compare these to. After having used these, you'll never want to use the cheap knockoffs again. Have used this with wires from 22-12 AWG with zero issues.The inside of these is where the quality is. The solid coil of metal really does an amazing job at biting into the wires to provide a solid connection that will last. Try giving it a nice pull once it's bottomed out and you'll noticed that hold stronger than Hodor can hold a door! The red part on these feels like some sort of rubber which is nice when trying to shove wires into it. They are very easy to hold on to even when you're wearing thick gloves.They come in a nice resealable bag which is nice if you only use a few here and there. I wouldn't hesitate to buy these again, and look forward to the many projects that will have strong and safe connections.
