by adding friction to the thread of the bolt. Different varieties of locking nut exist, those that utilize metal to create friction, such as the all metal nut, and those that incorporate a polymer in the design, such as the nylon insert nut.

Are lock nuts effective?

Also known as a stiff nut, a lock nut is a special type of nut that doesn't loosen when exposed to vibrations. ... While the use of two nuts is effective at preventing vibration-related loosening, it's not cost-effective for manufacturing companies that perform large-volume production operations.

When should you use a locking nut?

Locking nuts should be used when the screw joint consists of one or more soft materials. It is difficult to achieve and to maintain a high level of clamp load because the soft material deforms due to high surface pressure. This plastic deformation continues after the torque value has been applied to the screw.
