4.8 Color plated zinc hexagon bolts
Hexagonal bolts are a commonly used fastener with six flat corners that resemble a hexagonal shape. The head of the bolt can be rotated with a wrench or wrench to loosen or tighten the bolt. The size of the bolt head and the size of the threads are usually designed and manufactured according to standards, such as the international standard ISO and the national standard GB. Hexagonal bolts are usually made of carbon steel, stainless steel and other materials, and are widely used in machinery manufacturing, automobile manufacturing, construction engineering and other fields.
Anti-corrosion: Color zinc trivalent chromium film can effectively prevent the metal surface from oxidation, corrosion and other damage, prolonging the service life of the material.
Wear-resistant: colored zinc trivalent chromium film can improve the hardness and wear-resistant properties of metal materials, enhance their performance and durability.
Beautifying effect: Colored zinc trivalent chromium film can give different colors and glossiness to metal materials, thus increasing their aesthetics.
It should be noted that the color zinc trivalent chromium film contains hexavalent chromium element, containing toxic, very serious pollution of the environment.
Hexagonal bolts are mainly made of carbon steel and stainless steel.
Carbon steel hexagonal bolts are generally 4.8, 8.8, 10.9, 12.9, 8.8 or more are alloy steel, alloy steel material hardness and tensile properties are relatively high, this is also called high-strength bolts.
Stainless steel hexagonal bolts commonly used SUS201, SUS304, SUS316, etc., stainless steel bolts because of the material characteristics, its corrosion resistance will be better, and the appearance of more bright.
1, the application of mechanical manufacturing hexagon socket head cap screws is a common connectors, commonly used in mechanical manufacturing in a variety of equipment, such as machine tools, engines, manufacturing a variety of machines and tools. Hexagon socket head cap screws can withstand large torque, so it is usually used in application scenarios that require greater connecting force, such as connecting hydraulic pipes and piping connections.
2, the application of automobile manufacturing hexagon socket head cap screws are also widely used in automobile manufacturing. In the process of automobile manufacturing, hexagon socket head cap screws are very important fastening elements. Hexagon socket head screws are used in automobile engines, frames, chassis and other places, mainly due to the fact that this type of screws can ensure a stronger connection.
3, the application of building decoration hexagon socket head cap screws are also commonly used in the field of building decoration, such as engineering seismic, steel structure, metal structure protection, railroad track fixing and bridge construction. Hexagon socket head cap screws are able to fix various types of structures more firmly, and such screws can ensure that they will not loosen, thus reducing the cost of maintenance and repair. One of the main advantages of hexagon socket head screws is because of its hexagonal shape design, which makes it easier to tighten than other types of screws. Its design allows for better use of hand tools for torquing or removing it, which greatly reduces work time and labor.
