Square Washers are offered for applications where a round washer might not work. Square washers have a larger surface area than round washers with the same outside diameter. The larger surface area on square washers spreads loads over a larger area and also increases resistance. Square Washers are utilized to protect surface finishes and spread loads in a fastener assembly system that utilizes square headed fasteners.
