Cliff jack nut thread/diameter?

[Don Moose]

Is the nut on a Cliff jack a standard diameter and thread?
Have a jack that's pushed into the chassis because original nut/washer fell off; don't want to order and wait for a replacement jack just for the nut.

Thanks!

I have a small bin of nuts and washers I got from Ampeg in St. Louis when it existed. Haven't found a cliff jack they don't fit yet.
