Hexagonal cylindrical head flange bolts are a type of fastener that features a hexagonal head and a flange, which is a built-in washer that is part of the bolt head itself. This design allows for a larger bearing surface, distributing the clamping force over a greater area than a standard hex bolt, reducing the risk of damage to the materials being fastened. They are typically used in situations where a strong, secure connection is required.
Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.
Grade: The product grade is divided into A grade and B grade, as well as different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.
Advantage:
Increased Bearing Surface: The integrated flange provides a larger surface area, which can handle higher loads and reduce pressure on the connected parts.
Prevention of Loosening: The flange helps to prevent the bolt from loosening due to vibration or impact, providing a more secure connection.
Easy Installation: The hexagonal head allows for use with standard wrenches or sockets, making installation and removal straightforward.
Versatility: They are available in various materials, including stainless steel, which offers excellent corrosion resistance, and can be used in a wide range of applications.
Aesthetics: The flange provides a finished look, especially important in applications where the bolt head is visible.
Scope of
application
Automotive Engines: Used in the assembly of engines where a secure and reliable fastening solution is critical.
Heavy Machinery: Employed in heavy-duty machinery where high clamping forces and resistance to loosening are necessary.
Construction: Ideal for structural applications in buildings and bridges where the bolts are subjected to various stresses.
Pipe Flanges: Commonly used to secure pipe flanges, ensuring a tight seal and preventing leaks.
Aerospace: Utilized in aerospace applications for their high strength and reliability.
