    • An assembly unit includes a component including at least one through hole and at least one screw. The screw is associated with the through hole of the component. The screw is designed and arranged to produce a thread. The screw includes a head and a supporting surface to face the component. The screw includes a shank at least partly including a thread. The screw in the region of the shank and close to the supporting surface includes an annular channel, the diameter of the annular channel being less than the core diameter of the thread of the screw and the effective axial length of the annular channel being more than the axial length of the through hole. The diameter of the through hole of the component is more than the core diameter of the thread of the screw and being less than the outer diameter of the thread of the screw.
    • 组件单元包括包括至少一个通孔和至少一个螺钉的部件。 螺钉与部件的通孔相连。 螺钉被设计和布置成产生螺纹。 螺钉包括头部和面向组件的支撑表面。 螺钉包括至少部分地包括螺纹的柄。 柄部区域中靠近支撑表面的螺钉包括环形通道,环形通道的直径小于螺钉螺纹的芯直径,并且环形通道的有效轴向长度大于 通孔的轴向长度。 部件的通孔的直径大于螺杆螺纹的芯直径,小于螺杆螺纹的外径。

    • A fastener (1) for connecting at least two components includes a shank (4) having an axis. At least one threaded portion (7) is arranged at the shank (4), and it has a stressed cross section. At least one elongation portion (5) is arranged at the shank (4), and it has a stressed cross section. The stressed cross section of the at least one elongation portion (5) is less than the stressed cross section of the at least one threaded portion (7). At least one fitting portion (6) is arranged at the shank (4). It has a stressed cross section, and it includes a plurality of protrusions (9) and channels (10). The at least one elongation portion (5) and the at least one fitting portion (6) are spaced apart along the axis of the shank (4). The channels (10) have a root diameter determining the stressed cross section of the at least one fitting portion (6). The stressed cross section of the at least one fitting portion (6) is at least 20 percent more than the stressed cross section of the at least one elongation portion (5).
    • 用于连接至少两个部件的紧固件(1)包括具有轴线的柄(4)。 至少一个螺纹部分(7)布置在柄部(4)处,并且其具有应力横截面。 至少一个伸长部分(5)设置在柄部(4)处,并且其具有应力横截面。 所述至少一个伸长部分(5)的应力横截面小于所述至少一个螺纹部分(7)的应力横截面。 至少一个装配部分(6)布置在柄部(4)处。 它具有应力横截面,并且其包括多个突起(9)和通道(10)。 所述至少一个伸长部分(5)和所述至少一个装配部分(6)沿着所述柄部(4)的轴线间隔开。 通道(10)具有确定至少一个装配部分(6)的应力横截面的根部直径。 所述至少一个装配部分(6)的应力横截面比所述至少一个伸长部分(5)的应力横截面多至少20%。
