Beschreibung
Zusammenfassung:	The utility model discloses a U-shaped bolt and belongs to the field of mechanical parts. The U-shaped bolt comprises a U-shaped rod and two parallel screws. The free end of each screw is a threaded portion. The U-shaped rod and the screws are molded to be whole body. The interior arc surface of the U-shaped rod is provided with a plurality of anti-slip lines which are parallel to each other, and the length of each anti-slip line is one third of the external circumference of the U-shaped rod. The anti-slip lines are defined into the interior arc surface so as to be prevented from being excessively long to affect uses of the U-shaped bolt. According to the technical scheme of the utility model, the interior arc surface of the U-shaped rod is additionally provided with a plurality of anti-slip lines to increase friction between the bolt and a fastener, so that the U-shaped bolt is effectively prevented from loosening when in use.
