"I have used Nord-lock washers, they are demonstrated to be one of the most effective thread locking devices under heavy vibration, but as you say they are quite pricey." Which is odd, given their simplicity and ease of manufacture, etc. Can you get them stainless or just HDG ?

You can get them in various stainless alloys. My understanding is they have a really defensible patent.

  Their patent might have expired? Im not aware of the situation but these seem to be an identical product: https://heico-lock.us/ https://heico-lock.us/
