Electro - galvanized hexagon bolts are a common type of mechanical fasteners. Here is a brief introduction:
- Basic Structure: The head is hexagonal, which is convenient for tightening or disassembling with tools such as wrenches or sockets. The screw part is provided with external threads, which can be used in conjunction with nuts to fix two or more components together through threaded connections.
- Material Composition: Usually made of carbon steel, such as ASTM A307 carbon steel, which can provide a certain strength and durability.
- Surface Treatment: The surface is treated by electro - galvanizing, that is, a layer of zinc is coated on the surface of the bolt through electroplating. This treatment can provide basic anti - corrosion protection.
- Features: Compared with hot - dip galvanized bolts, the zinc layer of electro - galvanized hexagon bolts is thinner, and the corrosion resistance is relatively weaker, but it is suitable for mild outdoor and indoor environments. It has the characteristics of easy installation, and can provide a firm and stable connection, helping to resist movement.
- Application Scenarios: Widely used in various industries, such as in the electrical installation industry, it is used to fix circuit boards, shells, etc.; in furniture assembly, it is used for the splicing of tables, chairs, wardrobes, etc.; it can also be used in some light - duty projects, playing the role of connecting and fixing components.
