Prevailing Torque
A prevailing torque nut, also known as a self-locking nut or a torque-locking nut, is a type of fastener designed to resist loosening due to vibrations or external forces. Unlike standard nuts that rely on friction between the threads to maintain their tightness, prevailing torque nuts incorporate features that provide an increased level of resistance to rotation, making them less prone to coming undone.
Prevailing torque nuts are commonly used in applications where vibration, temperature changes, or other dynamic forces might cause traditional nuts to become loose over time. Some examples of industries and scenarios where prevailing torque nuts are used include automotive, aerospace, machinery, construction, and industrial equipment.
