Advantages of Hot Galvanized Hexagonal Bolts
In our work, we often use hot galvanized hexagonal bolts, which have many advantages and are loved by customers and developed rapidly in the market. Generally speaking, the top surface of hot-dip galvanized hexagonal bolts is marked with convex or concave characters, or concave characters are used on the side of the head, including performance [...]
Petrochemical Bolts
Petrochemical bolts are mainly used in the petroleum and chemical industries, and reasonable and safe use can achieve its maximum efficiency. Here is a brief introduction to how to use it correctly, so that everyone has a step closer understanding of petrochemical bolts. 1. It is best to use a drill bit that matches the [...]
A490 Hex Structural Bolt
A490 Hex Structural Bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws. A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench (spanner). An ASME B18.2.1 compliant cap screw has somewhat tighter [...]
Bolt Threads Processing
Bolt threads are usually processed by cold, so that the thread blanks in a certain diameter range can be formed by rubbing (rolling) the screw plate (die), and by the pressure of the screw plate (rolling die). The plastic streamline of the threaded part can be obtained without cutting off, the strength is increased, the [...]
Hexagonal Cylindrical Head Bolts
When inner hexagonal cylindrical head bolts are manufactured by cold heading process, the original structure of steel will directly affect the forming ability of cold heading process. The plastic deformation of local area in cold heading process can reach 60%-80%. Therefore, steel must have good plasticity. When the chemical composition of steel is constant, metallographic [...]
Bolt Quality
Bolt Quality: Nowadays, advanced manufacturing represented by large aircraft, large power generation equipment, automobiles, high-speed trains, large ships and large complete sets of equipment will enter an important development direction. As a result, fasteners will enter an important stage of development. High strength bolts are used for connection of important machinery. Repeated disassembly or various [...]
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 [...]
Connections of High Strength Bolts
The difference between friction type and compression type connections of high strength bolts: High-strength bolt connection can be divided into two types: high-strength bolt friction connection and high-strength bolt compression connection according to different design and stress requirements when shearing force is applied. The essential difference between the two types is that the ultimate state [...]
Difference between High Strength Bolt and Common Bolt
From the point of view of raw materials, material of High Strength Bolt and Common Bolt strength is different. High strength bolts are made of high strength materials. The bolts, nuts and washers of high strength bolts are made of high strength steel, commonly used in 45 steel, 40 boron steel, 20 manganese titanium boron [...]
Bolts Production Material
At present, the standard Bolts Production Material on the market mainly include carbon steel, stainless steel and copper. Carbon steel: We distinguish low carbon steel, medium carbon steel and high carbon steel as well as alloy steel with carbon content in carbon steel. stainless steel: Performance rating: 45, 50, 60, 70, 80. copper: Common materials [...]
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 [...]
Features and Application of Bolts
Hex Bolts Hex bolts are one of the most widely used types of bolts. Its Class A and Class B bolts are used for important applications where high assembly accuracy is required and subjected to large shocks, vibrations or alternating loads. Its C-class bolts are used in applications where the surface is rough and the [...]
Method of High Strength Bolts Fastening
The degree of tightening of ordinary bolts is not clearly defined, and the force applied during locking is generally as long as the connection is tight. However, since the tension is not applied when the lock is applied, the nut is prone to loosening. To prevent loosening, the inner nut can be pressed by the [...]
History of Bolts
The riveting bolts were still widely used until the 1950s, but the construction process of the riveting bolts was not only dangerous but also difficult for professional technicians. It also produced noise resistance during construction, and the construction quality was difficult to control due to the strength and clamping efficiency of the riveting bolts. In [...]
