3M wire nuts are the best in the business bar none! These style with the skirt on the bottom allow for bonded wires to be a touch long and it still covers the termination. The shell also expands to allow for above average capacity and guarantees a strong bond. These are the only wire nuts that I don't have to pre-bond with. I cannot say good enough things about these!

I have been using these 3m wire nuts now exclusively for several years. Because of the way they internally coil, they hold wires very securely. I have become a wire nut snob and replace all other wire nuts on sight.One very confusing thing when switching to 3M was that I did not understand the difference between the O/B+ and the T/Y+ nuts. I had to order both kinds to compare them. They are flat out identical and have the same specifications of wire sizes they work on. I have to assume there is some regulatory callout somewhere for the colors that force them to make them in both color combinations.I find myself using these small ones the most often in residential wiring as they take up very little space in electrical boxes. They are rated for up to three 12 gauge conductors.

Every wire nut has its shortcomings but this one is by far the best. You try the commercial electric from Home Depot or the waygo nuts, ideal wire nuts all of them just don’t seem to hold the wire firmly. I work with outside electrical most of the time and all of these other wire nuts fail and don’t hold up over time with our humidity but these hold up and don’t losen. They are the most functional high quality connections you’d ever want.

These wire nut handle a large range of splices. Their length is great for covering all the exposed copper of your splice. They are compact so that they do not take up lots of space in a small junction box.

After nearly 20 years as a maintenance man I will only use 3M wire-nuts, they grip better, hold better, on a wider range of gauges. When your two stories up on a ladder all you really want is for those 3 old, ugly, beat, misshapen, multiple gauge, multiple length, conductors to thread into the wire-nut and for it to bite. Real wire wrapping around each other positive bonding, not gonna have to climb back up here, not gonna have to re-install this fixture, no fumbling, confidence instilling bite. For safety, workman like manner, and my peace of mind it's 3M.

Works as intended. Does not come off like other connectors. Small form factor.
