Nylon or metal inserts inside a nut (sometimes called a lock nut) can add extra friction to prevent loosening. A related idea is to fit a spring inside the nut, which firmly grasps the bolt threads and is designed to move in the opposite direction of the nut if vibration or other forces cause it to unwind.
Which washer prevents a nut from coming loose?
Split washers also known as lock or helical spring washers are one of the most common mechanical devices bike owners use for this purpose. In theory, the washer is squashed flat when the nut is tightened against mounting surface so that its sharp edges dig in to prevent the threaded fastener unwinding.
How do you permanently lock a bolt nut?
Simply put a drop of liquid onto the bolt’s threads and secure the nut. When the thread locker is dry, the nut will be secure. NOTE: thread locking liquids come in different strengths. Some thread locking liquids are so powerful that heat or machinery will be required to remove the nut once the thread locker has dried.
What can I use instead of thread lock?
Superglue and nail polish as threadlocker alternatives are two of the most common, often quoted as effective replacements for dedicated threadlockers. Using these two products can indeed lock a fastener in place in the short term.

Superglue will be fine temporarily but it deteriorates when it comes in contact with water. However, as said above, no threadlock is fine. If the correct torque is applied and thread condition is ok so that it achieve designed bolt tension, it will never come loose.
How do you torque a nut?

Why are my nuts loose?
By far the most frequent cause of loosening is side sliding of the nut or bolt head relative to the joint, resulting in relative motion occurring in the threads.The off torque rotates the screw loose, if the friction under the nut or bolt head bearing surface is overcome, by this torque.
