Stainless steel square nuts are a kind of common fasteners, which are widely used in the mechanical engineering field3. Here is a detailed introduction:
- Shape and Structure: As the name implies, it is square - shaped. This design enables it to better adapt to some specific installation environments, and can provide better stability in some cases compared with other types of nuts.
- Main Functions: It can be closely connected with two or more parts to form a whole by cooperating with threaded bearings, so as to achieve the effects of fixing, supporting or transferring force. Using square nuts can reduce the loosening or vibration between parts and improve the efficiency and stability of the whole equipment.
- Production Standards: Usually produced according to standards such as DIN557.
- Common Materials: Often made of 18 - 8 stainless steel, and common grades include A2 (304), A4 (316), etc.
- Size Range: The common size range is from M5 to M24, and different sizes can meet the needs of different application scenarios.
- Surface Treatment: Usually, it will go through cleaning, passivation and other surface treatment processes to improve its corrosion - resistance and surface quality.
- Advantages: First, it has a simple structure, only a square head and internal threads, which is not easy to loosen or fall off during use. Second, the installation is convenient. During the installation process, it does not require special tools or fixing equipment, and only a conventional wrench can be used to complete the fastening. Third, it has a strong load - bearing capacity. Because its head is square, compared with other types of nuts, it has a larger contact area with the fastened parts, and the load - bearing capacity is stronger, which increases the safety of fasteners to a certain extent.
- Application Scenarios: It is mainly used on various mechanical equipment, especially in occasions where large transverse or lateral forces need to be borne, such as some connection parts of mechanical equipment, and can also be used in the connection of aluminum - profile structures.
