These lock nuts are designed to differentiate between a free-spinning nut and a locknut based on the torque required for installation before clamp loading. The torque needed, such as on a nylon-insert nut, surpasses the resistance caused by the nylon dragging across the mating thread. Typically, this torque is not excessively high compared to the final installation torque.

Our lock nuts, also known as lock nuts, locking nuts, self-locking nuts, prevailing torque nuts, stiff nuts, or elastic stop nuts, serve as essential components that resist loosening in the presence of torque and vibrations. Featuring a unique design, these nuts ensure secure fastening by flexing elastically to produce a locking action. Additionally, some variants spin freely, eliminating the need for additional torque until fully seated.
