The invention discloses an automatic detection and screening device for the hardness of a bolt fastening piece. The automatic detection and screening device comprises a charging part, a rotary table, a workpiece pressing part, a discharging part, a hardness meter and a table, wherein the charging part is fixedly arranged on a swinging platform mounting base; the swinging platform mounting base and the rotary table are mounted on a base of the hardness meter. The continuous and reciprocating motion of the charging part, the workpiece pressing part, the rotary table, the discharging part and the hardness meter realizes continuous multi-point hardness detection and screening of a bolt. According to the automatic detection and screening device, a movable part is driven by an air cylinder and an electromagnet; the control manner is simple and the work is reliable and easy to realize; an adjusting bolt on a driving piece, a gasket on a spring material stopping part, a workpiece positioning sleeve and a rotary baffl
