Wedge-Lock Washers

Wedge-Lock Washers In a general sense, the term "wedge-lock" implies a design that involves wedging or locking mechanisms to enhance the stability of the washer. These types of washers may have features that create a wedging action when the fastener is tightened, providing resistance to loosening caused by vibrations or dynamic loads. Bolted connections tend to work themselves loose under certain operating conditions. Vibrations cause particular problems as they can overpower the “self-locking effect” of bolted connections. This can lead to functional failure or even lead to the connection coming apart. As it’s not always possible to know what forces are acting on the structure, and as constructional measures cannot be implemented everywhere, securing elements are often used.
