The head of the Square neck T bolts is a horizontally placed "T" shape, just like the letter "T". This wide T-shaped head enables the bolt to be stuck in the T-shaped groove of the equipment, playing a role in preventing the bolt from being pulled out.
Square neck T bolts are used for mechanical manufacturing of fixed components. In mechanical manufacturing plants, they are used for the installation of many mechanical equipment components. For instance, machine tools have various complex components that need to be precisely fixed to ensure their normal operation for processing parts. T head bolts with square neck bolts can be flexibly installed in T-slots at different positions according to the design of the machine tool, firmly connecting each component together to ensure that the components will not loosen due to vibration or other reasons during the operation of the machinery.
Square neck T bolts are used in the assembly process of automobile production. There are many metal parts in a car that need to be assembled, such as the connection of some structural components of the car chassis. It can provide stable fastening force, allowing all parts of the chassis to be closely combined, ensuring the strength and stability of the chassis during driving. When the car is running, it has to withstand the impact force brought by various road conditions, and these bolts need to be able to withstand it.

Square neck T bolts are highly recognizable. Viewed from the side, the part where the head connects to the screw, that is, the neck, is a regular square, neat and square. Moreover, the length of the neck is usually not too long and is generally about the same thickness as the component it is connected to. The screw part is a cylindrical metal rod, and its thickness varies according to the specifications of the bolt. The surface of the screw is engraved with threads, which are similar in shape to the common bolt threads we see, in a spiral shape, and are used to tighten the nut.
