In some important occasions and we'll take some anti-loosening measures to ensureNutReliability. Wherein the use of the lock nut is one of them against rotation. Nut works by usingNuts and boltsThe friction between the self-locking. However, in such a dynamic load lock reliability is reduced.
      Locknut in three ways:
      The first is to use two of the same with a nut on the bolt, between two nuts to attach a tightening torque, so that the bolt connection is reliable.
      The second is dedicated locknut, and need a way to lock washer together. Dedicated locknut not hex nuts, but a round nut, ball screw nut on the circumference opened (depending on the nut size and manufacturer product line varies) 3-8 gap, which is both a few notches tighten the focal point of the tool, but also snaps into place lockwashers bayonet.
      The third is on the outer surface of the nut to the inner circumferential surface of the threaded screw hole drilled through the (usually 2 to 3, leaving it in the outer uniform) for screwing the small-diameter countersunk screws, the purpose of applied to a threaded radial direction of force to prevent the lock nut loosened.
