NUT AND SCREW LOCK

Lock nuts with nylon inserts (self‑locking nut, locking nut) are a prevailing torque, locking nut that resists loosening caused by vibration and normal use. Unlike free spinning nuts, lock nuts make use of a deforming elastic or metal material to stay in position against torque and shock. 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.
