Functions of Hyperload nut. 

When attached to a bolt, a spring installed in a nut stretches circularly and vertically and shrinks back. By these force, the spring itself adheres to the screw thread and blocks out a force of the nut's loosening.

However, when removing from a bolt, a user pushes and loosens the release end, and by doing so he or she may unlock the spring's force when it is necessary.

Moreover, this function of loosening prevention can be sustained and the user can use this function repeatedly.
