The Nordlock washers shown here are pretty much industry standard in the oil
industry. They work excellent.
Different principle from a spring washer but very simple.
They are the only type approved for secondary retention on overhead loads
offshore.

OK, here's a pic of a "Junker Test" setup. It holds the bolt head
stationary and only moves 1/2 of the bolted joint.
In situations similar to that in the real world (like on a Spridget) I think
we use Castellated nuts.
I can't think of a real world situation that is similar to the "Junker
Test". Does anyone know of one?
I wonder how the "Junker Test" does with chemical bonds (Loctite), and other
forms of mechanical lock washers, besides the ones the video producers are
trying to sell.
