As a Master Electrician, these are my go to wire nuts for small fixture wires. Perfect when doing ballast bypass LED upgrades to old fluorescent 4' fixtures.

Bought a pack of these to wire multi sized wires together for a tight outdoor lighting. All the other wire nuts were much bigger. Good solid binding of wires range from 16 to 22.

Bought these and the comparable ideal nuts. The ideals are easier to use and appear to be better quality. The ideal nuts also accept 4 # 12 while these accept 3 # 12. Both have the flex inlet and are small making them easy to install into an electrical box. The box was beat up a little and appeared older stock.

Professional grade. We used these in the electrical trade so, naturally, when I used all of mine up doing stuff around the house it was an easy go-to for ordering more. They're slightly higher price but well worth the premium. The threads bite and hold the wire inside every time w/o fail. Some of the cheaper ones can sometimes not bite well enough and could lead to issues that you'll need to track down later (at best). The wings on the sides allow you to get better torque to twist wires together for more positive connectivity. The insulation skirt is great for providing that little bit of extra safety buffer to the exposed wires inside. I wish all items I buy had this obvious of a front runner in terms of quality products. This is one of those items that, if you never try anything else, you won't know how great they are because they just work every time and stay where you put them. Once you use inferior wire nuts, you'll understand the value of these. Is it possible to be in love with a wire nut? lol

I was introduced to these years ago by an electrician friend of mine. Unlike the typical hard cases yellow or orange ones these grab like nothing else. If you are an “overtightener” like me these give great feedback and I haven’t managed to strip one out yet. Made so well I am not afraid to reuse if needed. The flexible jacket is a nice touch, adds some flexibility and space in. Tight junction boxes. As an average handy homeowner I buy the smaller packages as they will last years.

Slips on quickly & easily, binds with wires together tightly & uses much less space in the junction box.

I will never buy anything else than 3M wire nuts. They thread on like butter and hold like nothing I've ever seen. The rubber on the end prevents connectors or ground wires from touching the conductors.Trust me, they changed my whole view on screw on wire connectors.

I had bought a container of 1000 of these wire nuts years ago and have used them extensively in my job of heating and cooling repair. I love these nuts. :D They work very well with many different sizes and types of wire from stranded 10 gauge to solid 22 gauge and any mix thereof. They hold tight and grip well and the blue rubber skirt gives extra protection against shorting and electrocution. They easily screw onto various sizes of wires and come off again cleanly if needed. Made by 3M so the expected quality is there and they hold up well in all climates from 112º to -10º, from the blistering sun to the damp crawl space under an 80 year old 3 bedroom. When I started to run out a couple of months ago I went looking for more only to find that I could not buy them anywhere local. Was facing the prospect of having to use those inferior cheap plastic wire nuts that I have come to hate for their ability to rip the small wires in two under their caps and their equally frustrating ability to not screw onto the big wires no matter how hard I tried to get them to "take".Went looking online for these wire nuts and found them on Amazon. Bought two boxes hoping they were the same quality wire nuts that I had bought nearly a decade ago and waited for them to arrive. Two days later I received them and opened the box, I was elated to discover that yes, they are the same product that I have come to love and that the price was reasonable for such a fine piece of workmanship. Don't laugh, you cannot understand what its like to crawl under a house at 2 am on Christmas eve, dragging your tool bag behind you as you inch your way towards the non-functional furnace that is sitting 40 feet away from the entrance, only to discover that the crappy wire nuts you have in your tool bag will not screw onto the wires and now you have to crawl back out for more and redo it all again. Let me just say that I have probably invented a few new words as I made that trek. Long story short, these wire nuts from 3M just work. I will be buying a few more boxes.
