Exploring the Characteristics and Uses of Stainless Steel Combination Screws
Stainless steel combination screws are mostly used to connect thin metal plates and are fasteners that play a connecting role.
Stainless steel combination screws are divided into stainless steel two-combination and stainless steel three-combination, with a wide variety of categories.
In the combination screw, the washer should be able to rotate freely without falling off. Stainless steel combination screws are easy to use, no need to match flat washers or spring washers, easy to use, greatly improving production and assembly efficiency.
- Standard
There are many types of combination screws, let's take the most commonly used ones as an example.
Commonly used stainless steel combination screws are: stainless steel cross pan head three-combination GB9074.4, stainless steel cross recessed hexagon three-combination GB9074.13, stainless steel outer hexagon three-combination GB9074.17, etc.
The material of stainless steel combination screws is stainless steel SUS304 and SUS316, and the performance grades are A2-70 and A4-70 respectively.
SUS304 stainless steel is the most commonly used material for stainless steel combination screws. 304 stainless steel has a moderate hardening rate and is suitable for general cold processing and drawing. It has good cold processing performance and is commonly used in products such as screws, bolts, nuts and washers.
316 stainless steel has more molybdenum added than 304 stainless steel, and has stronger corrosion resistance than 304 stainless steel. It is also called acid-resistant steel and is particularly suitable for seawater and chemical media.
Stainless steel combination screws are generally not surface treated, only need to be cleaned and polished. To improve corrosion resistance, passivation treatment can be used.
- Installation
Different types of stainless steel combination screws have different occasions and functions. For example, cross pan head three combination screws are generally used in small electronic products. Larger cross hexagon combination bolts are used in larger electrical products, such as inverters, and are hit on the inverter housing for loosening and tightening.
- Application
Stainless steel combination screws, as a high-performance connection element, have penetrated deeply into multiple industrial fields and have won wide acclaim for their excellent corrosion resistance, high strength and excellent heat resistance. In the electrical industry, due to the precision of circuit boards and the strict requirements for conductivity, stainless steel combination screws have become the preferred fasteners for circuit board assembly with their stable performance and excellent conductivity. In the field of electrical manufacturing, whether it is large household appliances or small electronic products, combination screws play a key role, ensuring the stable connection between various components and improving the overall stability and durability of the product.
In the field of mechanical equipment, stainless steel combination screws are even more indispensable. In high-speed mechanical equipment, the stability of the screws is directly related to the safe operation of the equipment. With its excellent fatigue resistance and high strength, stainless steel combination screws ensure the stability and reliability of mechanical equipment during long-term operation. In addition, in the field of shipbuilding, stainless steel combination screws also play an important role. When ships are operating at sea, they often face the test of harsh environments such as salt spray and humidity. Stainless steel screws ensure the stability and safety of ship structures with their excellent corrosion resistance.
In the fields of chemical industry and water conservancy, stainless steel combination screws also play an irreplaceable role. Chemical equipment is often exposed to various corrosive media, and the corrosion resistance of stainless steel screws can ensure the stability of the equipment during long-term operation. In water conservancy projects, stainless steel screws are also widely used due to their excellent performance, providing a solid guarantee for the safe operation of water conservancy facilities.
In summary, stainless steel combination screws have become an indispensable fastener in modern industry with their excellent performance and wide application fields. Whether it is electrical, electrical, mechanical equipment or shipbuilding, chemical, water conservancy and other fields, it can be seen. In the future, with the advancement of science and technology and the development of industry, stainless steel combination screws will continue to play an important role and provide strong support for the progress and development of various industries.
