Hexagon flange bolts, also known as hex flange bolts, are a type of fastener that features a hexagonal head with an integrated flange plate.The flange provides a larger bearing surface, which helps to distribute the load and protect the joint surface from damage during tightening.These bolts are designed to be used with nuts to fasten and connect two parts with through holes.
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 Area: The flange provides a larger bearing surface, which helps to distribute the load and reduce pressure on the fastened parts.
Self-Locking: Some hex flange bolts come with a serrated flange, which can help prevent the bolt from loosening due to vibration.
Corrosion Resistance: Depending on the material and surface treatment, these bolts can offer good corrosion resistance, making them suitable for various environments.
High Torque Tolerance: The design of the hex flange bolt can withstand higher torques, ensuring the tightness of the fastener.
Simplified Assembly: The integrated flange eliminates the need for additional washers or spacers, streamlining the assembly process.
Scope of
application
Automotive industry, especially in truck and heavy vehicular frames.Construction and structural engineering where a large bearing surface is required to distribute the load.Machinery and equipment where a flush finish is needed or where there is limited space for installation.Applications requiring high clamping force and vibration resistance, such as in engines or heavy machinery.
