Abstract

The invention discloses an axle end nut for a car. The axle end nut for the car comprises a nut body, wherein a screw cap is arranged on one end of the nut body, and at least two mortises are arranged on the end surface of the other end of the nut body; the mortises extend along the axis direction of the nut body; and a bump is formed between the mortises. According to the invention, the mortises and bump are arranged on the end surface of the nut body to match with other non-smooth components, so that the defect that the axle end nut easily loosens is avoided.
