Good basic lock nut
I used this recently on a wood project and it provides a solid lock on a 3/8" bolt. The bolt can be run all the way through the lock nut as well. This nut basically keep the bolt from becoming undone as there is a nylon washer inside the nut.

These are the best nuts I ever saw!! When you use them with the correct bolts they hold things together and if you tighten they right they won’t come off! Highly recommended!! (Really? you’re asking me to review a nylon lock nut?)
