Default Keyed washer not a "lock washer"

The keyed washer seen on many threaded headset was never intended to
act as a "lock washer". The key way system was intended to keep the
lower adjustable race from turning as the top locknut was tightened.
In theory, this means you can use only one wrench, and not hold the
lower race. In practice, it is necessary to use two wrenches, one to
tighten the top nut and a second to hold the lower race. If fact, you
can find many threaded bikes where the keyed washer has rotated into
the thread, cutting and damaging them. The keyed tab is effectively a
"tooth", doing far more damage than good.

Once again, we see it is tension in the threads that holds the
fastener system secure. Get it tight.

Why the hell does this person keep posting outside the threads he
obviously intends to comment on?
