Galvanize plated Anti corrostion Metric Hex Bolt Carbon steel Hot Dip Coarse Thread customize pitch

1,Description:

Hexagonal bolts have the following significant advantages over other fasteners:

1. Superior mechanical properties• High torque transmission efficiency: The hexagonal design provides a large contact surface between the wrench and the bolt head, making it less likely to slip and enabling it to withstand a greater tightening torque
• Strong load-bearing capacity: The head is not prone to deformation or stripped (slippage), making it suitable for high-load connections
• Uniform force distribution: The hexagonal structure ensures a more balanced stress distribution, reducing local fatigue damage

2. Good ease of operation• Strong tool versatility: Standard hex wrenches, socket wrenches, and ratchet wrenches can all be operated, and the tools are readily available
• Multi-directional operation: It can be disassembled and assembled from multiple angles on the side (one every 60°), with good spatial adaptability
• Fast and efficient: When combined with electric/pneumatic tools, it can achieve rapid batch assembly, enhancing production efficiency

3. Standardization and interchangeability• Unified international standards: Adhering to standards such as ISO, DIN, and GB, the specifications are globally universal, and procurement and replacement are convenient
• Complete range of specifications: Parameters such as diameter, length, and pitch are serialized and complete, meeting the requirements of various working conditions

Hot-dip galvanizing is an anti-corrosion process in which steel components are immersed in molten zinc to form a metal coating, and it is widely used in construction, automobiles and other fields.

The definition of hot-dip galvanizing

Hot-Dip Galvanizing is a process in which steel products that have undergone cleaning and activation treatment are immersed in molten zinc. Through chemical reactions, a zinc-iron alloy layer is formed, effectively preventing the corrosion of steel materials. This process combines physical barriers and electrochemical protection, featuring excellent corrosion resistance and adhesion.

Process flow

The basic process flow of hot-dip galvanizing includes the following steps:

1. Pickling: Remove iron oxide and impurities from the surface of steel.

2. Water washing: Clean the steel parts after pickling.

3. Pre-plating treatment: Use ammonium chloride or zinc chloride solution for treatment to enhance the adhesion of zinc.

4. Drying: Dry the treated steel parts.

5. Immersion plating: Steel parts are immersed in molten zinc at approximately 450℃ to form a zinc layer.

6. Cooling and cleaning: After taking it out, cool it down and clean it to remove the excess zinc slag on the surface

2,Applications:

Machinery Manufacturing: Equipment assembly, base mounting
Construction Engineering: Steel structure connections, bridge construction
Automotive Industry: Engine and chassis assembly
Electronics and Electrical: Enclosures, equipment housings
Furniture Manufacturing: Metal frame structures
Pipe Installation: Flange connections
