My Steady Fast System came with Lock Nuts that are installed on the threaded rod after the wing nut is installed.
The lock nut keeps the wing nut from unscrewing and falling off.
Maybe they have changed the kit since I bought mine.
Been coast to coast with my Steady Fast in the last two years and have not lost anything
