M4 M5 M6 Carbon Steel Male And Female Hex Head Standoff Black plating Metal standoff

 
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.

In order to improve the rust resistance of steel parts, a strong oxidising agent is used to oxidise the surface of the steel parts into a dense, smooth layer of iron tetraoxide. This thin layer of iron tetraoxide effectively protects the interior of the steel part from oxidation. At high temperature (about 550℃) the oxidised iron tetraoxide is sky blue, so it is called bluing treatment. In the low temperature (about 350 ℃) formed by the formation of iron tetraoxide is dark black, so called blackening treatment. In the manufacture of weapons, commonly used is the blue treatment; in industrial production, commonly used is the blackening treatment.
 

Can the steel surface oxidation dense, smooth iron tetraoxide, the key is to choose a good strong oxidising agent. Strong oxidising agent is composed of sodium hydroxide, sodium nitrite, trisodium phosphate. When bluing, their molten solution is used to treat the steel; when blackening, their aqueous solution is used to treat the steel.

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.
