An automatic screw feeding apparatus includes a base assembly, a slide assembly, a first spring, a screw carrier driving device, and a screw carrier guidance device. The slide assembly is mounted to the base assembly, movable forward and backward between a first position and a second position along a straight path. The first spring is mounted between the base and slide assemblies for keeping the slide assembly at the first position. The screw carrier guidance device includes a connection member connected with the base assembly, a guide member mounted to the connection member and movable forward and backward between a third position and a fourth position, and a second spring mounted between the guide and connection members for keeping the guide member located at the third position. The second spring can greatly lighten the load of the first spring to prevent the fed screws from being jammed.
