Agreed, Alan.
I also have five Fastenal's nearby. I'm going to see what they have
available to replace the small split washer that already exists on top
of the OR2800. The bolt is a small 1/4"-20 and the split washer has a
measured outside diameter of .488 dia. The pocket in the bottom of the
mast centering device is .506 in inside diameter.
See http://www.w4abc.com/OR2800_Centering_dimensions_op_800x475.jpg and

Looking through the McMaster-Carr catalog, there are two 1/4" sizes
available in SS but the following has an outside dia. of .450 -

There are also two of the zinc coated variety in 1/4" with the following
also having a .450 outside dia. -

The second application where I think these Nord-Lock washers may have
merit is on the bottom of the rotator. I've seen the safety wire/bolt
kits for sale, but it's tight quarters in-between the tower braces to
wind safety wire for the inexperienced.
