Disclosed is a threaded fastening assembly, comprising: a stud (1), having an external thread (101); a first connecting part (2), provided with a first screw hole (201) adapted to the stud (1); and a second connecting part (3), provided with a second screw hole (301) adapted to the stud (1) and the directions of the threads on the first screw hole (201) and the second screw hole (301) being opposite to each other. The first connecting part (2) and the second connecting part (3) are mounted on two ends of the stud (1) via the first screw hole (201) and the second screw hole (301) respectively; when rotating the stud (1) along one direction, the first connecting part (2) and the second connecting part (3) are engaged facing each other; when the first connecting part (2) and the second connecting part (3) are completely engaged, the stud (1) is accommodated in the first screw hole (201) and the second screw hole (301). In the threaded fastening assembly, the screw head design in conventional threaded couplings is dispensed with, which not only saves space but also avoids the thread head affecting the appearance of a product when being exposed on the outside. |
