Grade 4.8 Zinc Plated Hexagon Bolt

Grade 4.8 zinc plated hexagon bolt is a type of fastener consisting of a head and a screw (cylinder with external threads), which is used in conjunction with a nut to fasten two parts with a through-hole. This form of connection is called bolt connection. If the nut from the grade 4.8 zinc plated hexagon bolt down, and can make the two parts separate, so the bolt connection is a removable connection.

Advantages

Wide range of strength: The tensile strength of grade 4.8 zinc plated hexagon bolt is not less than 400MPa, and the yield strength is not less than 320MPa, which is able to meet the needs of general mechanical connections, building structure connections and many other conventional engineering application scenarios, such as the assembly of common mechanical equipment, building steel structure of some non-critical parts of the connection and so on.

Lower cost: Compared with high-strength grade bolts, 4.8 grade bolts in the production process of raw material requirements are relatively low, the manufacturing process is relatively simple, do not need to go through complex heat treatment and other processes to improve the strength, so its production cost is lower, in the more stringent cost control of the project has a greater advantage.

Good processing performance: Grade 4.8 zinc plated hexagon bolt material hardness is moderate, easy for cutting, drilling, tapping and other machining operations, can efficiently produce bolts in line with the requirements of dimensional accuracy and surface quality, but also conducive to the installation of the site for the necessary secondary processing, such as adjusting the length of the bolt.

Installation advantages

Grade 4.8 zinc plated hexagon bolt because its strength is not particularly high, in the installation process, the use of ordinary tools such as wrenches and so on can be tightened operation, do not need to use a special high-strength bolt installation tools, reducing the difficulty of installation and installation costs, but also improve the efficiency of the installation.

In some common electrical housing or internal component connections, grade 4.8 zinc plated hexagon bolt can provide sufficient tightening force at a lower cost.

Application

General mechanical equipment: In some mechanical equipment that does not require high strength, such as some simple mechanical assembly or connection of light equipment, grade 4.8 zinc plated hexagon bolt can meet the basic fastening needs.

Furniture Manufacturing: In furniture assembly, grade 4.8 bolts are commonly used to connect wood panels, plates and other components, and their economy and moderate strength make them common fasteners in furniture manufacturing.

Construction: In the construction structure, such as some non-load-bearing connection parts or light construction structure connection,grade 4.8 zinc plated hexagon bolt can also play its role!
