M3 M2.5 Blue Yellow Galvanized Male And Female Hex Head Standoff Carbon Steel hexagon studs


Product Description:

What is a standoff? As the name suggests, the standoff is a screw with internal thread at one end and external thread at the other end, and the broad sense of the standoff also includes screws with internal threads at both ends. Its appearance is hexagonal, play a role in fastening and isolating, because it is generally made of hexagonal copper rods as raw materials, so the standoff is also known as copper column, hexagonal copper column, copper isolation column or copper gasket column.
The use of copper columns. Hexagonal screws are mainly used in computers, circuit boards and other industries, when one end is screwed into the locked object, the hexagonal column is exposed to the outside, which can fix or isolate other objects.
The main specifications of standoff are M3, M4, M5, M6, M8, M10, etc., and the specifications of the hexagonal column are 5, 6, 8, 10, 12, 15 mm, etc., of which the M3 series is the most. Materials in addition to copper and stainless steel, there are fast cutting steel.

Hexagonal studs are also known as yin and yang studs, it is one end of the internal thread and one end of the external thread, but are hexagonal, can play a role in fastening and isolation.

Mostly used in computers, circuit boards and other industries, when used, when one end is screwed into the workpiece being fastened, the hexagonal column is exposed on the surface, can be fixed or isolated from other workpieces. Such as in the computer mainframe, the external thread can be connected to the motherboard inside the mainframe, the internal thread can be isolated from the motherboard and sheet metal shell.

Applications:

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218 per cent to 2.11 per cent. It is also called carbon steel. Generally also contains a small amount of silicon, manganese, sulfur, phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness, the higher the strength, but the lower the plasticity.
Classification
(1) According to the use of carbon steel can be divided into carbon structural steel, carbon tool steel and free-cutting structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two;
(2) According to the smelting method can be divided into flat furnace steel, converter steel;
(3) According to the method of deoxidation can be divided into boiling steel (F), sedentary steel (Z), semi-sedentary steel (b) and special sedentary steel (TZ);
(4) According to the carbon content of carbon steel can be divided into low carbon steel (WC ≤ 0.25%), medium carbon steel (WC0.25%-0.6%) and high carbon steel (WC ≥ 0.6%);
(5) according to the quality of steel can be divided into ordinary carbon steel (containing phosphorus, sulphur higher), high-quality carbon steel (containing phosphorus, sulphur lower) and high-quality steel (containing phosphorus, sulphur lower) and high-quality steel.

Cost

Another important consideration is the cost difference between carbon steel and stainless steel.

Although different steels have different costs, stainless steel is generally more expensive than carbon steel.

This is primarily due to the addition of various alloying elements to stainless steel, such as chromium, nickel, and manganese.

All these extra elements in stainless steel add to the cost compared to carbon steel.

On the other hand, carbon steel consists mainly of relatively cheaper elements of iron and carbon.

If you are on a tight budget for your project, then carbon steel may be the best option.

Stainless Steel:
1, the basic knowledge of stainless steel
Stainless steel is an alloy material with corrosion resistance, and its main components are an alloy of elements such as iron, chromium and nickel. These elements can effectively resist oxidation and corrosion, so that stainless steel has a high degree of durability and aesthetics.
2, stainless steel maintenance methods
Cleaning
Keeping stainless steel products clean is an important part of their maintenance. You can use mild detergents and soft cloth for cleaning, avoid the use of detergents containing acidic and alkaline components, so as not to damage the surface of stainless steel. When removing dirt, you should try to avoid using irritating cleaning tools to avoid scratching the stainless steel surface. After cleaning, rinse with water and dry with a clean soft cloth.
3, the use of stain remover
For some stubborn dirt, you can use special stainless steel stain remover for cleaning. But before using it, you should carefully read and follow the instructions in the product manual. In addition, stainless steel products on the dirt can be cleaned with alcohol or vinegar, these common cleaners on stainless steel has a certain decontamination effect.
Steel types:

Stainless Steel vs Carbon Steel - Composition:
The main difference between stainless steel and carbon steel is their composition.

Carbon steel, as the name suggests, consists mainly of iron and carbon. The carbon content ranges from 0.03% to 2.0% by weight, depending on the grade. This carbon content affects the mechanical properties of the steel, such as strength, hardness and ductility. Carbon steels may also contain traces of other elements such as manganese, sulphur and phosphorus.

Stainless steel, on the other hand, is an alloy with an iron content of at least 10.5 per cent chromium by weight. This chromium content gives stainless steel its corrosion-resistant properties, making it ‘stainless’. In addition to chromium, stainless steel may contain other alloying elements such as nickel, molybdenum and nitrogen, depending on the grade. These additional elements further enhance the corrosion resistance, strength and other mechanical properties of stainless steel.

Stainless steel and carbon steel - Properties and applications:
Due to their different compositions, stainless steel and carbon steel exhibit different properties and are therefore used in different applications.

Carbon steel is relatively cheaper and more widely used than stainless steel. It has good strength and ductility and is suitable for a wide range of applications including construction, automotive and machinery. However, its susceptibility to corrosion is a major limitation. Carbon steel requires regular painting or coating to prevent rust and corrosion, especially in wet or corrosive environments.

In contrast, stainless steel stands out for its corrosion resistance. It can withstand exposure to water, acids, alkalis and other corrosive agents without rusting or deteriorating. This makes stainless steel ideal for applications where durability and longevity are critical, such as the food processing industry, medical equipment and chemical plants. In addition, stainless steel's aesthetic, easy-to-clean and hygienic properties make it popular for use in cookware, surgical instruments and architectural elements.
