Washers are vital components for assembly and fastening processes for successful operation; washers are the essential assembly component. Washers can be used under the head of the fastener, bolt, screw, or under the nut or a combination. Washers are designed to perform various functions in particular applications; these may be locking, load spreading, protection, decorative, tension indicating, sealing, or a combination of all these roles. Washers are also crucial for preventing galvanic corrosion, mainly by insulating steel screws from other material surfaces.
