M4 M6 Galvanized Male And Female Hex Head Standoff Carbon Steel Coated blur zinc standoff

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.

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.

• 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
• According to the smelting method can be divided into flat furnace steel, converter steel
• 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)
• 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%)
• 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

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.
