In the highly sophisticated and safety demanding industry of cell modules, the choice of fastening products is directly related to the performance, stability and safety of the products. Among them, the extended hexagon three-combination screw, especially the style with flat spring pad, has become a widely used fastening product in this field because of its unique design and excellent performance. Below, we will take an in-depth look at why this screw is so important in the core module industry, and discuss in detail its advantages, fastening capabilities, and the performance of specific specifications such as 6*180 hexagonal three-piece screws under 72-hour salt spray testing, as well as the advantages of environmentally friendly blue and white zinc surface treatment.
First, design advantages
1. Hexagonal design
The hex socket design is one of the core advantages of this screw. The hex design provides a more uniform torque transfer when tightening than traditional straight or Phillips screws, reducing the risk of slippage and damage. At the same time, the use of the hex wrench also makes the installation and disassembly process more simple and fast, improve the work efficiency. The convenience of the hexagonal design is particularly prominent in the case of the core module, which requires frequent maintenance and replacement of parts.
2. Three combination structure
The extended hexagon three-combination screw consists of a screw body, a flat washer and a spring washer. This design not only increases the reliability of fastening, but also effectively prevents the screw from loosening under vibration or external force through the elastic action of the spring pad. The flat pad increases the contact area between the screw and the workpiece, further improving the fastening effect. The synergistic effect of the three combination structures makes this screw perform well in applications such as core modules that require high strength fastening.
Second, fastening ability
1. High strength materials
The core module requires very high strength of fasteners, because any loosening may cause damage to the core and even cause safety accidents. Therefore, lengthened hexagonal three-set screws are usually made of high-strength materials, such as stainless steel or alloy steel. These materials have high tensile strength and shear strength, and can withstand the huge pressure and vibration generated during the operation of the core module.
2. Customize specifications
Taking the specific specification of 6*180 as an example, its long screw length and moderate diameter design allow this screw to penetrate deeply into the multi-layer structure of the core module to achieve deeper tightening. At the same time, by adjusting the length and diameter of the screws, the core modules of different thicknesses and apertures can be flexibly responded to to ensure the consistency of the fastening effect.
72-hour test of salt spray
Salt spray test is an important means to measure the corrosion resistance of fasteners. In the application environment of the core module, it often encounters bad conditions such as damp and salt spray. As a result, the extended hexagonal triple set screws verified by the 72-hour salt spray test ensure stable fastening performance and good corrosion resistance despite prolonged exposure to harsh environments. This is of great significance to improve the service life and safety of the core module.
Four, environmentally friendly blue and white zinc surface treatment
1. Environmental protection
With the increase of environmental awareness, more and more industries are beginning to pay attention to the environmental performance of products. As an environmentally friendly coating process, the surface treatment of blue and white zinc not only has good corrosion resistance, but also can reduce the pollution to the environment. This surface treatment process makes the application of lengthened hexagonal three-piece screws in the core module industry more in line with environmental requirements.
2. Aesthetics
In addition to environmental protection, environmentally friendly blue and white zinc surface treatment also gives the screw a beautiful appearance. In the core module such a product with high requirements for details, beautiful fasteners can not only improve the overall texture of the product, but also enhance the brand image to a certain extent.
V. Summary
In summary, the extended hexagonal three-set screw occupies an important position in the core module industry with its unique design, excellent fastening ability, corrosion resistance through the 72-hour salt spray test and the advantages of environmentally friendly blue and white zinc surface treatment. This screw not only improves the stability and safety of the core module, but also reduces the maintenance cost and work difficulty. With the continuous development of battery module technology and the continuous expansion of application fields, we have reason to believe that this screw will play a more important role in the future.
