I'm not very mechanically inclined, so I've come to you experts for a few questions regarding nylock nuts.
My brother owns a boat down in Florida. Before taking it out recently, he had some work done on the steering system. It appears the mechanics removed the nylock nut, and didn't replace it with a new one. A couple days later, the nut backed out, and the steering system became detached, and we lost control of the boat. We hit some rocks (because we couldn't steer), and it caused a lot of damage. We've been told that you're not suppose to re-use these nylock nuts. Is that true?
Does salt water impact the effectiveness of nylock nuts?
Should nylock nuts be re-used, or replaced?
Are there other, safer nuts that could have been used, to avoid this?
Or, was this just "one of those things"?
Any help or insight would be appreciated. Thanks!!!
