Wow! One Wire Nut For 22-12 Gauge Wire!!
I was hanging a light recently and didn't have the right color/size connector, so when I saw these it was a no-brainer. This size covers most types of DC and AC wiring I do, from 22-12 gauge. My son is a union electrician and he recommended these Ideal nuts over others because he uses the next larger size regularly. He also told me a great way (see photo) to more easily twist these nuts... a socket! This size Ideal nut fits perfectly into a 12mm metric socket. They also fit into a 1/2" socket, but 12mm is a more snug fit. The standard 12mm socket worked, but the deep well 12mm was perfect, as the nut sort-of clicks into it and stays in place. I found a spare 12mm 1/4" drive deep socket and bought a 1/4" socket to 1/4" hex drive adapter (Dewalt DW2541) for a couple bucks. Now when I need to screw on wire nuts, I simply put the end of the hex drive socket into my hex screwdriver (or drill). Safety Note: Obviously, turn off the power first and use a plastic handled screwdriver to insulate yourself from the metal socket and driver shaft just in case. This isn't an issue with the Klein hex driver I use. These are great quality, super versatile wire nuts!!

Works well, high quality, good feel
Nice and high quality. Fits in tight spaces and easy to screw on with wings but aren’t too large that it gets in the way.

Equal quality as night at big box stores
Much cheaper per versus buying at Home Depot or anywhere in America. Works just the same.

Great for contractors
These are a go to for our shop of electricians. This was a great price, but I was disappointed to not be able to order the smaller wire nuts in a larger container quantity. We go through these very fast and these small containers don’t last long. These twist on well every time, but always pre-twist wires. The protector sleeve is a great feature.
