Metric lock nuts have a "locking" element that prevents the nuts from free spinning after the element engages the mating threads. For metric all metal lock nuts nuts, thread deformation creates the prevailing torque, which may cause thread galling. Reuse is limited since the prevailing torque declines each time the nut is installed and removed.
