What is the structure and function principle of T-head bolt?

A bolt is a common connection element, usually composed of a screw and nut. The structure of the bolt mainly includes thread, screw groove, head and tail. The thread is the core part of the bolt and is used to fit with the nut to form a threaded connection. The screw groove is the groove in the bolt that is used to install the bolt and rotate the bolt through a wrench or spanner. The head is the end of the bolt that is used to rotate the bolt so that it connects or loosens with the nut. The tail is the other end of the bolt, which is used to fix to the workpiece being connected.

The action principle of bolts is mainly realized through threaded connection. When the bolt is driven into the nut, the friction between the bolt and nut prevents them from separating from each other, creating a solid connection. By tightening or loosening the bolt, the fastening force of the bolt connection can be adjusted to meet different working environments and requirements. In addition, because the bolted connection has a large internal friction and tensile strength, it can withstand a large tensile force and shear force, which is suitable for the connection of various mechanical equipment and structures.

In general, bolts, as an important connection component, have a wide range of applications in machinery manufacturing, automotive, aerospace, construction and other fields. Through the bolted connection, the solid connection between the workpiece can be realized to ensure the normal operation of the machine and equipment, improve the work efficiency and ensure the work safety. Therefore, the structure and action principle of bolts is a basic knowledge that must be understood by engineers and technicians in all walks of life.
