摘要： A pre-load indicating washer in which a plurality of protuberances, struck and partially sheared from the annular body of the washer, are pushed under load back into a corresponding of indentations in the annular body which are formed when the protuberances are formed. The walls of the protuberances and the walls of the indentations are arranged so that when the protuberances are "collapsed" back into the indentations, there is minimal frictional resistance as the walls of the protuberances slide past the walls of the indentations.

摘要： A pre-load indicating washer in which a plurality of protuberances, struck and partially sheared from the annular body of the washer, are pushed under load back into a corresponding plurality of indentations in the annular body which are formed when the protuberances are formed. The mass of material defined by each protuberance/indentation pair is concentrated along the lengthwise central region of the protuberance/indentation pair, thereby stiffening the protuberance, so that when load is applied to the washer, the protuberance will first undergo elastic deformation prior to collapsing back into the indentation from which it was formed.
