发明名称 SELF-DRILLING FASTENING ELEMENT
摘要 The invention relates to a self-drilling fastening element (10), comprising a rotationally symmetrical drilling tip (16) and a shaft (14), wherein the cross-section of the drilling tip (16) is bounded by a first radius (R2), the origin (22) of which lies outside the rotational axis (18) of the drilling tip (16) on the side opposite the rotational axis (18), near the drilling tip (16), and a second radius (R1) near the shaft (14), wherein the origin (26) of the second radius (R1) is farther from the rotational axis (18) than the origin (22) of the first radius (R2) and likewise lies on the opposite side of the rotational axis (18).
