Ok, My family manufactured boats. We found the best lock nut was the nylon
insert type. We never had one come loose. You can wear the nylon out if you
take the nut off and on allot...but you have to do it many times.
Also there is "Locktight threadlocker."
This stuff is great too

We called them "Crown nuts" trouble with theses are you have to drill the
hole for the pin in the bolt yourself. -James KB4RMN
