Abstract:
A fastener assembly (1) includes a screw (2) and a bush (3). The screw (2) includes a head (4), a shank portion (6) and a threaded portion (7) including a thread (8). The shank portion (6) is arranged to face the head (4) and the threaded portion (7) is arranged to face away from the head (4). The shank portion (6) has a diameter and the thread (8) has an outer diameter, the diameter of the shank portion (6) being smaller than the outer diameter of the thread (8). The bush (3) includes a first narrowing location (10) having a diameter being smaller than the outer diameter of the thread (8). The bush (3) is captively connected to the screw (2) by the first narrowing location (10). The bush (3) includes at least one resilient element (15) having an actuation portion (28) and an engagement portion (29). The actuation portion (28) in an unmounted position of the fastener assembly (1) extends from the outer circumference of the bush (3) in a radial direction in a way that the engagement portion (28) does not engage the thread (8) of the threaded portion (7). The actuation portion (28) is designed and arranged to be pressed in an inward direction in a pre-mounted position of the fastener assembly (1) in a bore (22) of a component (20) such that the engagement portion (29) engages the thread (8) of the threaded portion (7).
