What is the main function of hex screws in use?

Hexagonal screws are a common type of fastener mainly used to connect two or more materials. There are many different types, including external hexagonal screws and internal hexagonal screws.

External hexagon screws are commonly used for connecting large equipment, suitable for thin-walled parts or situations subjected to impact, vibration, or alternating loads. They can also be used for situations with a wider range of full thread lengths, such as situations where shear caused by lateral forces needs to be withstood.

One advantage of this type of screw is its self selling property, which means that once it is inserted, it will automatically stay there and not easily fall off. However, its disadvantage is that it takes up a large space and is not suitable for some delicate occasions.

Hexagonal socket screws are commonly used for connecting small devices and mechanical connections that require high aesthetic and precision requirements. The biggest advantage of this type of screw is that it can be easily tightened and disassembled with a specialized wrench, and it is not easy to slip, which improves work efficiency.

At the same time, due to its ability to be directly embedded inside the workpiece, it looks more delicate and beautiful, and does not hinder the operation of other components. However, its disadvantage is that it has a small contact area and relatively small pre tightening force, which may not be suitable for some situations that require bearing large loads.

In short, hex screws are widely used in various machinery and equipment, with high practicality and economy. During use, it is necessary to choose the appropriate hex screw according to the specific situation to achieve good results.
