What's about this product:
A locknut, also known as a lock nut, locking nut, self-locking nut, prevailing torque nut, stiff nut, or elastic stop nut, is a nut that resists loosening under vibrations and torque.
Feature:
Prevailing torque nuts have some portion of the nut that deforms elastically to provide a locking action. Free-spinning locknuts exist which carry the advantage of not requiring extra torque until seated.
Application:
Effective torque differentiates lock nuts from free-spinning nuts by the value of how much torque is required before clamping loads during installation. For example, on a nylon insert nut, it is the torque required to overcome the resistance of the nylon to drag over the mating threads. This torque value is usually not very high relative to the final installation torque. Some standards specify the tolerance range of torque
