    they are lock nuts, they will not come off if they are not tightened all the way. But with that said the bolt will not do its job if it is not tight. So tighten them! And when you take the locknuts back off replace them because they wont lock properly the seconded time.

    Lock nuts should be tighten the same as a standard nut. The lock function is there to keep vibration from shaking them loose over time.

    Tighen them down.

    How come toro doesn't put lock nuts on the handles of it's 21 inch mowers?

    Even though I duck tape them up, I still end up losing some of those things. I'm thinking I should try this stuff I saw at home depot called thread locker. I think it's just glue you put on the thread.

    also, if you don't tighten them down all the way and the bolt is vibrating around against the metal it passes through, it will tear the threads up and then you'll have to replace the bolt.

    Tighten them down. A lock nut can still come loose from vibration. Also over time the nyloc part will take the shape of the threads and render it useless as a locking nut.
