Provides soft, uniform friction between two surfaces.
Provides less load build up and more flexibility than a standard disc washer, it offers a wide range of flexibility.
Intended for maintaining a uniform pressure between surfaces, not for repeated flexing.
Developed for use in electrical boxes, slotted washers are sometimes referred to as electrical washers.
