Steve - Thanks for the link to the article.? I learned something from your comments and that article. Roger

Like you said Steve, they're everywhere, and they're still considered acceptable even in aviation. Critical locations though will use better locking hardware. I wouldn't want to rely on split ring

Lots of info.. bit ott..its a wellbrock on a mast.. Blue locktight, plus nylock locking nut against a plain washer..job done..( on just about anything on land.) only thing that can be an issue is too

You could use a jam nut that way but you risk moving both nuts together and have little or no locking. When applying a jam nut you use both hands and two wrenches. The procedure and detailed
