Exactly what you are hoping for
I install appliances and love using these on wall ovens and cooktops. Most electricians haven't even seen these before. They are much easier to use that traditional BX connectors because they just screw into the armored casing and don't need a screwdriver. If replacing appliance down the line, you an usually leave the connector in the JB and just unscrew the casing and put a new wire in. Satisfying to put the new one in; just rotate backwards till tension and watch it thread on.

Got what I wanted. . . . .
This item actually delivered on my part. They advertised 50 pieces and I got 50 pieces. The box the parts were in looked kinda like it was 20 years old but I didn't care about that. The parts looked like they were sitting on a shelf for a long time when I inspected the contents. "BEWARE" just because something is advertising bulk amount does not mean your gonna get the bulk amount. I was screwed 2X in 1 week. I'm happy that this item was not one of the screw overs.
