Abstract
A multi-head self-threading bolt comprises a bolt head and a bolt body, characterized in that the bolt body is provided with at least two screw teeth having different heights. Since the bolt body is provided with the screw teeth having different heights, the multi-head self-threading bolt of the utility model can not only advance the connecting intensity of the thin-wall workpiece but also prevent thin-wall workpiece from breaking, thereby achieving the purpose of the utility model.
Description
Technical field
The utility model relates to hardware, specifically is meant a kind of bull tapping screw.
Background technique
The hardware of using always when tapping screw is the workpiece connection, when the connection that is used for thin-wall part, thread is little, and join strength is not enough, and thread is big, is easy to generate to break.
The model utility content
The purpose of this utility model is that the structure of above-mentioned screw is improved, and proposes a kind of thin-wall part that is applicable to and connects the bull tapping screw of usefulness.
The purpose of this utility model is achieved in that a kind of bull tapping screw of the present utility model, and it comprises the screw head and the body of screw, it is characterized in that having at least on the body of screw two kinds of threads that height is different.
Bull tapping screw of the present utility model because the different thread of height is arranged, both can improve the join strength of thin-wall workpiece on the body of screw, can prevent that again thin-wall workpiece from breaking, and reaches the purpose of this utility model.
Description of drawings
Fig. 1 is the structural representation of bull tapping screw.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of bull tapping screw of the present utility model, it comprises the screw head 1 and the body of screw 2, and height different thread 3 and thread 4 are arranged on the body of screw 2.
Claims (1)
1. bull tapping screw, it comprises the screw head (1) and the body of screw (2), it is characterized in that having at least on the body of screw (2) two kinds of thread (3) and threads (4) that height is different.
