A fastener assembly includes a drive shaft, a threaded shaft, and a joint portion. The drive shaft is used for being operated to rotate around an axis thereof. The threaded shaft has a thread thereon, and is used for being screwed into an object. The joint portion is used for connecting the drive shaft with the threaded shaft. The joint portion is able to transfer the rotation of the drive shaft to the threaded shaft, and allow the rotations of the drive shaft and the threaded shaft about different axes.
