Description

Technical Field

[0002] A self-tapping screw is a screw with a drill bit that is constructed with a special power tool to complete drilling, tapping, fixing and locking in one go. The head of a self-tapping screw usually has a spike or drill guide, which helps it cut into the material and form threads when screwed in. During the process of screwing in the self-tapping screw, its threads will be embedded in the pre-drilled hole and drill further into the material along the thread direction, forming a solid connection. The design of the self-tapping screw enables it to fix the material at a certain depth without the use of other tools or brackets.

[0003] Due to the different screwing angles of self-tapping screws, the stress on the self-tapping screws will change. For connection structures with high precision requirements, it is necessary to ensure that the self-tapping screws are stably screwed at the corresponding angle. Most traditional self-tapping screws are not equipped with a stable structure and have poor screwing stability. In actual use, self-tapping screws often deviate when screwing. Utility Model Content
