摘要

a selbststanzendes hollow einpresselement (10), in particular mutterelement for attachment to a metal sheet (40) has a larger diameter flanschteil (12) and a schaftteil (14) of smaller diameter. the schaftteil (14) extends from the flanschteil (12) way and shows his the flanschteil (12) turned away stirnende (16), a circular stanzkante (18).the schaftteil (14) side of the flanschteils (12) forms an annular blechanlageflu00e4che (22) and (24) are verdrehsicherungsmerkmale on schaftteil (14), from approximately the height of the blechanlageflu00e4che (22) on a part of the length of the schaftteils (14) in the e ntlang).radially within the annular blechanlageflu00e4che (22) is an annular reinforcement (26) in the flanschteil (12) are provided. excess material (28) of the schaftteils, by manufacturing the verdrehsicherungsrippen (24) is located within the annular reinforcement (26).
