Abstract
In the large-area washer with an aperture for fastener means, there are engagement components on the surface in the fastening direction of the washer. The engagement components engage a cover strip that is to be fastened. The washer also has stiffeners in the form of beads. Unreinforced corner regions of the washer lie radially outside the stiffeners relative to the aperture and can be elastically resiliently bent about an imaginary line at an acute angle to two central axes of the washer. Engaging components may be formed in these corner regions.
