Processing of Bolt Head and Thread

How is the bolt head and thread processed? The head of bolt is formed by cold upsetting plastic processing. Compared with the cutting process, the metal fiber (metal wire) is continuous along the product shape without cutting off in the middle. Therefore, the strength of the product is improved, especially the mechanical properties are excellent. [...]

Hexagonal Bolt Materials

There are three kinds of Hexagonal bolt materials: carbon steel, stainless steel, copper. Carbon steel: We distinguish low carbon steel, medium carbon steel, high carbon steel and alloy steel by carbon content in carbon steel. 1. Low carbon steel C% ≤ 0.25% is usually called A3 steel in China. It is called 1008101510181022 in foreign [...]

Bolt Manufacturing Process

Annealing: The wire is heated to a suitable temperature for a certain period of time, and then slowly cooled to adjust the crystal structure, reduce the hardness, and improve the normal temperature processability of the wire. Pickling: removes the oxide film on the surface of the wire and forms a phosphate film on the metal [...]
