This is going to sound stupid but what is hardened mean?

Hardened stainless steel?

You can buy hardened wire (piano wire) a most hardware stores.
0.93" is what you want....although if a tail grommet needs to go into it you'll need to enlarge the hole so for production work a larger wire might be better.
This is also good for a pull wire if you want to pour lead directly into your plug (I don't)
The stuff is very hard and you will need something with a lot of leverage and hardened jaws to cut it
PAM works for lubricant
