Just picking fly poop out of pepper, like most of members that post replies.
The term "scotchlok" does not mean anything without addition context. As I said all wire connectors made be 3M are covered by the term scotchlok.
If you ask a phone guy for a scotchlok, you will probably get the button type insulation displacement connector used for the small gauge wire in phone cables. If you ask an electrician, you will probably get a wirenut.
 
Using wirenut as a generic term for a twist on wire connector. Is "wirenut" trademarked term?
Ideal has trademark name "Wire-Nut" for this particular one of their products. I think it is only available in three sizes being color coded orange yellow and red. Other trademarked product lines of theirs are called Wing nut, Twister, Twister Pro, Twister Pro FLEX.

It has been a number of years ago that Wire-nut had a display at one of our CEU and trade show events 'Win a Shotgun' if you could pick the original. It was the Orange one. We used them exclusively for ballast replacements back when.

You mean like these? Have found a few of those before, mostly on the K&T.

You can still purchase the ceramic ones. They usually marketed for use with high temperature situations and high temperature conductors. I think Pretty sure I still have a small bag of them that I purchased several years ago, likely used two or three for something I intended them for when I purchased them and still have the rest of what was in the bag.

Back when I was in school for this trade out in the lab area we would thread a drywall screw into the open end and out the cap end, the yellows were nearly perfect fit in 1/2" EMT to make a blow gun out of it. We would shoot them at targets placed on a bulletin board in the lab.

Drywall nails and rolling a cone shaped piece of paper. Something to do on breaks.
