I've been wondering for some time why Nord-lock type washers are not used on our birds. They have a neat design that uses tension in the washer to rather than friction in the locking nut to provide the locking action. They are touted to be particularly good in high vibration environments. Interesting video here: https://www.youtube.com/watch?v=IKwWu2w1gGk
I finally came across a set in my Matco brakes; the AN4 bolts that hold the pad opposite the plunger have Nord-like type washers. It's a bolt into a blind hole, so safety wire or Nord-locks are the only way to secure them.
My question to the VAF brain trust: Why aren't these washers used more frequently? On my IO-360, all the bolts use the ancient star washers as "lock washers." It sure seems they get smashed down pretty flat after one use. Is it the price?, love of pre Wright bro's technology, or some other reason(s)?
