Prevailingtorquenötter
Prevailingtorquenötter, commonly known as prevailing torque nuts or self-locking nuts, are fasteners designed to resist loosening due to vibration and torque. Their mechanism relies on creating a higher friction force between the nut and the bolt threads than would be present in a standard nut. This increased friction prevents the nut from backing off under dynamic loads.
There are several types of prevailing torquenötter, each employing a different method to achieve self-locking. One
Another type utilizes an integrated locking element, such as a nylon insert or a metal cap, which
Prevailing torquenötter are widely used in applications where vibration is a significant concern, such as in
