Further, one end of the bolt head, which is far away from the washer, is provided with a recess.
Further, the recess is a circular blind hole.
Further, the depth of the recess is 0.1-0.4 of the thickness of the bolt head.
Furthermore, the tail end of the connecting part is provided with a chamfer.
The utility model also provides a bolt connecting pair which comprises the large hexagon bolt, the single chamfer washer and the nut, wherein the single chamfer washer and the nut are arranged on the connecting part.
The utility model has the following advantages:
according to the large hexagon bolt, the integrally connected washer is arranged on one side of the bolt head, when the large hexagon bolt is used, the washer does not need to be placed below the bolt head, the phenomenon of reverse placement or missing placement can be avoided, and in addition, the installation efficiency of the bolt connection pair is improved.

Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the utility model will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the utility model and that it is not intended to limit the utility model to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, there is provided a large hexagon bolt, as shown in fig. 3 and 4, including a bolt head 11, a washer 13 and a connecting portion 14, where the washer 13 is a single-sided chamfered washer, a side face of the washer 13 having a chamfer faces a direction of the bolt head 11, the bolt head 11 and the washer 13 are integrally connected, another side face of the washer 13 is connected to the connecting portion 14, and a part of a surface of the connecting portion 14 is provided with a thread.
According to the large hexagon bolt, the washer 13 is integrally connected with one side of the bolt head 11, when the large hexagon bolt is used, the washer 13 does not need to be placed below the bolt head 11, the phenomenon of reverse placement or missing placement can be avoided, and in addition, the installation efficiency of a bolt connection pair is improved.
The bolt head 11 is provided with a recess 12 at the end remote from the washer 13. By providing the recess 12, the fixing can be facilitated.
The recess 12 is a circular blind hole. By providing the recess 12 as a circular blind hole, on the one hand, machining is facilitated and, on the other hand, the strength of the bolt head 11 can be ensured.
The depth of the recess 12 is 0.1-0.4 of the thickness of the bolt head. The depth of the recess 12 should not be too shallow to risk the tool slipping out during fixing, but, of course, should not be too deep to affect the strength of the bolt head 11.
The connecting portion 14 comprises a threaded section 141, the tail end of the connecting portion 14 is provided with a chamfer, namely the tail end of the threaded section 141 is provided with a chamfer, a single-chamfer washer and a nut are conveniently mounted when a large hexagon bolt is used, and connection is achieved.
The embodiment of the utility model also provides a bolt connecting pair, which comprises the large hexagon bolt, the single chamfer washer and the nut, wherein the single chamfer washer and the nut are arranged on the connecting part 14, when the bolt connecting pair is required to be connected, only one single chamfer washer and one nut are required to be arranged, compared with the prior art that two single chamfer washers and one nut are required to be arranged, the installation efficiency is improved, and the probability that the washers are easily placed reversely or leaked is reduced.
Although the utility model has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
