In a large-area washer (1) there is an aperture for the insertion of a fastener and a bead (16) to stiffen the washer (1). To pro- vide better engagement with a plate and/or web to be fastened there are engagement compo- nents (13) on the underside of the washer (1) which are pressed out of the whole material of the washer (1) and project approximately per- pendicularly downwards from it. The engage- ment components (13) are conical or truncated cones.

Une rondelle à grande surface (1) comporte une ouverture (5) conçue pour l'introduction d'un élément de fixation et un bourrelet (16) de renforcement. Des éléments de contact (13), destinés à faciliter le montage sur une plaque et/ou sur une bande à fixer, sont situés sous la rondelle (1) et emboutis dans la totalité du matériau constituant la rondelle. De forme conique ou tronconique, ils sont quasiment perpendiculaire à la rondelle (1).
