Why does the nut not screw in all the way?
We use a nylon insert locknut. It's a nut with a nylon ring inside of one end. The nylon ring is narrower than the diameter of the bolt and will stretch around it when torqued. The side without the nylon ring is threaded onto a bolt first. Once the nut is twisted onto the bolt the nylon works to keep the nut locked in two ways. First, it increases the friction between nut threads and bolt threads by causing the bottom faces of the bolt threads to press more tightly against the top faces of the nut threads. Second, the nylon itself is pressing on the bolt, creating more friction.
Since the nylon bounces back to its original form when removed from a bolt, it can be reused many times.
It may seem that the nut will not twist through but give it a bit more torque and tighten as desired. This system eliminates the need to overtighten the bolt and nut.
