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. [...]

Classification of High Strength Hexagon Socket Bolts

The High Strength Hexagon Socket Bolts connection is to clamp the plates of the connecting plate by a large amount of tightening pre tension in the bolt bar, which is enough to produce a great friction force, so as to improve the integrity and rigidity of the connection. When subjected to shear force, according to [...]

Bolt Classification Knowledge

Bolt Classification Knowledge This time Fastener Bolt Exporter talks about bolt information other than threads. There are many types of bolts, and there are probably several classification methods: classification by the head of the bolt; classification by the material; classification by the performance level; classification by the connection force method. The first category is classified [...]

Advantage of High Strength Bolts Nuts

High-strength bolts nuts connection has many advantages, such as simple construction, good mechanical performance, removable, fatigue resistance, and no loosening under dynamic load. It is a promising connection method. High strength bolt is a special wrench to tighten the nut, so that the bolt produces a huge and controlled pre-tension, through the nut and cushion [...]

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 [...]
