Alas, his box only has the sizes on it!
Jack (my fiancee's father) always calls them "zeus fasteners..." But what would he know.
Hopefully Jack wasn't spelling it like you do, but I don't know what he knows.
I worked with "zeus" fasteners, too, when I was an auto mechanic and helped with my boss's race car. I knew how to spell it AND pronounce it. When I was told to get "zeus" fasteners, I looked for the box with "Dzus" written on it.
Look it up if you don't believe me. Here's a start.
