The photos all seem to come up with round pins; did I miss something?

The gland nuts I'm dealing with have rectangular notches. Pins might
work, but they seem precarious.

The snap rings you pictured are often called Eaton rings, though most
I've encountered are hard.

Thanks, that's a term I've not encountered before.
