These washers are heat-treated to a high hardness so that they can be used in very high load applications, when a standard washer may be distorted by the extreme pressure, causing it to provide a poor bearing surface. This is especially useful in cases where the hole for the bolt is oversized or mishapen, or the substrate is not perfectly flat.
