3M Performance Plus Wire Connector T/R+POUCH, Tan/Red, Flexible Steel Spring Connectors, Copper, CSA Certified, UL Listed, Pouch of 100, 22-8 AWG

These grip very well! So much safer than those other brands! But these!

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.

I love these. This is the preferred ones I use. Work every time. I don’t like the all reds or yellows. I look for these first.

There's simply no comparison with the Chinese wire nuts offered on Amazon for ridiculously cheap prices. The 3M is far, far superior and given what you're asking it to do, you really should spend the extra money for the designed-in-Minnesota version.For starters, the actual thing itself is more versatile. This covers the size range of both the reds and the tans.But even within the item, it's hugely better. The red skirt at the bottom is flexible and the tan is more rigid, making it "comfortable-r" (at least as comfortable as hand twisting a large # of these can be).Inside is the real kicker. The spring which "bites" into the bare wires and ties them together is actual, strong, angled steel. Meaning it kind of cuts and bites into the copper and has a very good tension. If you cut this open vs. a cheap Chinese wire nut you will see the Chinese one has a crappy, round-wire shiny spring which can be pulled apart by your fingers and has no angle to bite into the copper. In fact the Chinese springs often fall out because they're so loose -- meaning you might accidentally put on a nut with no spring and have a bad connection. Not with the 3Ms.I threw away all the Chinese ones and went 100% with these Tan/Red 3Ms except for a bag of Orange/Blue for the rare 14G or smaller connections.

These little guys make twisting wires so much easier. Definitely worth the little extra to avoid the headache and time trying to twist wire into a standard wire nut. Never going to use anything else again.

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.

They are great and more efficient than carrying two sizes.

Not sure about these! Compared to the Red/Yellow they don't seem to work as well.

Didn’t think I’d love a wire nut. You can really feel it sinch down. Love them.
