Adding a nyloc nut to Toolbox...

Unless someone can tell me otherwise, I can't seem to find nyloc nuts in the Toolbox. Someone at my work did download a nyloc and place it in the toolbox area of our PDM, but it has several mate issues.

I tried pulling up a toolbox nut to look at the mate references so that I could try to find out how to set the mates up properly - but that was no help.

Can someone instruct me how to set these mates up properly? A link, or video, would be greatly appreciated.

AND, will I be able to choose the correct size like I can with standard toolbox components? I am assuming that my nyloc would have to have the different configurations for the different sizes as well.
