Abstract: A nut for fastening a first workpiece defining a through recess to a second workpiece including a bolt projecting in an axial direction through the recess, and the nut comprises an axially extending shank and flange at a first end of the shank, and the nut defines a bore extending axially through the flange and into the shank and further defines an opening to the bore proximate to the first end of the shank, and the nut further includes an elastic holding section radially outward of the opening, and the nut partially defines a depression radially outward of the holding section, so that the holding section can flex radially outward into the depression when the nut is jammed onto the bolt.

Abstract translation: 用于将限定通孔的第一工件紧固到第二工件的螺母，所述第二工件包括沿轴向突出的螺栓穿过所述凹部，并且所述螺母包括在所述柄的第一端处的轴向延伸的柄和凸缘，并且所述螺母限定一个 所述孔径向延伸穿过所述凸缘并进入所述柄部，并且进一步限定靠近所述柄部的所述第一端部的所述孔的开口，并且所述螺母还包括位于所述开口的径向外侧的弹性保持部分，并且所述螺母部分地限定凹陷部 在保持部分的外侧，使得当螺母卡在螺栓上时，保持部可以径向向外弯曲到凹陷中。
