  • Patent number: 5597279
    Abstract: A washer for a male or female threaded fastener includes an annular ring portion and a seat portion with a cantilever portion extending therebetween. The washer hardness is selected to exceed the threaded fastener hardness by an amount that enhances the elastic deflection of the washer and reduces the tendency of the fastener to loosen. The selected hardness relationship also reduces the washer diameter dilation during loading and the permanent deformation of the washer diameter.

  • Patent number: 4971498
    Abstract: A cantilevered washer for a male or female threaded fastener having a conical seat portion including an conically-shaped seat for receiving the threaded fastener in such maner as to load the washer at an angle and relieve hoop-stress on the threaded fastener. The washer further has an annular ring portion including a flat annular base for mating with a surface of a part being fastened. The annular ring portion and the conical seat portion are connected by a cantilever portion which is inclined at an angle of substantially 45.degree. to the flat bearing portion in order to provide a low profile vertical displacement between the conical seat portion and the flat bearing portion, as well as provide a location for deflection of variable bearing loads.
