Expansion bolts with yellow zinc plated surface

The wall thickness of the expansion pipe of the elevator expansion bolt is thicker than that of ordinary expansion bolts of the same specification; The expansion pipe of elevator expansion bolts is longer than that of ordinary expansion bolts of the same specification; Several additional grooves have been added to the expansion pipe of the elevator expansion bolt to increase its tensile strength; The screw head size of elevator expansion bolts is larger than that of ordinary expansion bolts; Elevator expansion bolts are equipped with spring washers,that prevents the nut, from loosing after installed. This product is suitable for fastening connectors of heavy objects such as elevators. It is made of high-quality steel material, with strong seismic tension and gripping force. Generally, the compressive strength of reinforced cement concrete is not less than 25MPa. Its installation operation is the same as that of ordinary expansion bolts.
