Types and tightening methods of hexagonal flange screws？

Hexagonal flange screws are a very common type of screw, characterized by six corners on the bolt, resembling a hexagon in shape. Due to its simple structure and convenient installation, it is widely used in industrial production. There are many types of it, and it is necessary to choose correctly and master the correct fastening method.
The types are as follows:
1、 SUS304 stainless steel flange screw
The flange screws made of SUS304 stainless steel material have strong corrosion resistance, acid and alkali resistance, high-temperature resistance, and no rusting. Therefore, it is more common in practical applications.
2、 Carbon steel flange screws
Carbon steel flange screws are the common type, which are not only very affordable but also have outstanding performance. They have high strength and hardness, so they can meet the needs of mechanical equipment.
3、 Brass flange screw
A brass hexagonal flange screw is a type of screw, which is mainly composed of two metal alloys: copper and zinc. The screw has a bright appearance and is corrosion-resistant, making it very suitable for applications that require corrosion protection.
4、 Copper flange screw
Copper flange screws are a type of screw suitable for specific occasions. Unlike traditional screws, they have outstanding electrical conductivity. Generally used in electronic instrument applications.
5、 Titanium alloy flange screws
Titanium alloy flange screws are usually used in the high-end mechanical field and are highly favored due to their relatively lightweight and long service life. Meanwhile, the strength of this type of screw is comparable to that of steel, making it a very cost-effective choice.
Tightening method:
Firstly, use a hex wrench to complete the tightening work. Without a hex wrench, using other tools may cause screws to be damaged or loose. Therefore, using a hex wrench helps to ensure the safety and stability of the tightening work of the hex flange screws.
Secondly, it is important to choose the appropriate length of flange screws. If the length of the screws is too short, they cannot fully penetrate the components and therefore cannot be tightened. If the length of the screws exceeds the component, they will puncture the component and cause damage. Therefore, confirming the correctness of the length is a very important step in the process of tightening the flange screws.
Also, be careful when tightening to avoid damaging the screw head. Even force needs to be maintained when tightening. This helps to ensure uniform tightness between the screw head and flange, avoiding unnecessary issues such as looseness or leakage.
In addition, it is necessary to carry out inspection work after tightening. Check if the hexagonal flange screws are fully tightened and if there are any signs of looseness or separation. In addition, check for any abnormal conditions such as deformation or damage to the components and screw heads. It can be said that the correct selection and installation of flange screws according to the prescribed method are important steps to ensure the safe deployment of industrial production.
