A cone washer or cone spring washer is a type of washer that has a conical shape. It is used to resist loosening under vibration or dynamic loads. It comes with a circular shape and a tapered edge, allowing it to be inserted into a bolt or screw head to provide a spring-like tension.
Cone Washer
Cone washers are typically used in applications where vibration and dynamic loads can cause fasteners to loosen over time, such as in the pumps, compressors, and generators of industrial machinery. They can also be found in automotive applications—in engine mounts, transmission mounts, and suspension components to prevent the bolts and screws from loosening.
