Hexagonal flange bolt is a commonly used fastener, and the following is a detailed introduction to it:
Structural composition
The hexagonal flange bolt consists of three parts: hexagonal head, flange plate, and screw, and is an integrated bolt.
Hexagonal head: There are usually two types: flat head and concave head. It is the part where a wrench or other tool is used to tighten a bolt. Its hexagonal design allows the wrench to apply better force when tightening or loosening the bolt, and it is less likely to slide.
Flange: located below the hexagonal head and fixed together with the hexagonal head, its size varies depending on the usage scenario and requirements, and there are flat bottomed and toothed flanges. The toothed flange can provide anti slip function, increase the friction between the bolt and the connecting components, and prevent bolt loosening.
Screw: It is a cylindrical body with external threads that, when combined with a nut, achieves the function of fastening and connecting two through-hole parts.
Performance characteristics
High preload force: Compared with ordinary bolts, hexagonal flange bolts have a larger ratio of support area to stress area, which allows them to withstand higher preload force and provide more reliable fastening force when connecting components, ensuring the stability of the connection.
Good anti loosening performance: The design of its flange and the way it fits with the nut make the hexagonal flange bolt have good anti loosening performance. When subjected to external forces such as vibration and impact, it is less likely to loosen compared to ordinary bolts, thus ensuring the safety and reliability of the connecting parts.
Easy installation: The hexagonal head shape facilitates the use of tools such as wrenches for operation, and the installation process is relatively simple and fast, which can improve work efficiency.
Good corrosion resistance: According to different usage environments and requirements, the surface of hexagonal flange bolts can be treated with various methods, such as white plating, green, color yellow, Dacromet, etc. These treatment methods can enhance the corrosion resistance of bolts and extend their service life.
Material and performance grade
Material: Common materials include carbon steel, stainless steel, etc. Carbon steel hexagonal flange bolts have high strength and hardness, suitable for general mechanical connections and structural fixation; Stainless steel bolts have good corrosion resistance and are commonly used in applications that require high rust prevention, such as food processing equipment, medical devices, outdoor facilities, etc.
Performance level: The performance level of flange bolts used for steel structure connections is divided into more than 10 levels, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9, etc. Among them, bolts of grade 8.8 and above are made of low-carbon alloy steel or medium carbon steel and undergo heat treatment (quenching, tempering), commonly known as high-strength bolts, while the rest are commonly known as ordinary bolts. The bolt performance grade number consists of two parts of numbers, which respectively represent the nominal tensile strength value and yield strength ratio of the bolt material.
application area
Hexagonal flange bolts have a wide range of applications in various fields, including but not limited to the following aspects:
Industrial and civil buildings: In the connection of building structures, such as steel frames, bridges, factories, etc., hexagonal flange bolts are used to fix beams, columns, trusses, and other components to ensure the stability of the building structure.
Mechanical manufacturing: Various mechanical equipment, such as cars, cranes, excavators, machine tools, etc., require the use of hexagonal flange bolts to connect components during assembly to ensure the normal operation and safety of the equipment.
Pipeline installation: In pipeline systems, it is used to connect flanges, ensure the sealing and firmness of pipeline connections, and prevent pipeline leaks.
