Hexagonal flange face bolts, are bolts with a hexagonal head and an outwardly extending flange face. This design provides a larger support surface, which helps to reduce stress on the connected parts and prevent damage during connection. Usually manufactured to DIN 6921, they are a common type of fastener used in industrial applications.
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:
1. Enhanced Load Distribution: The flange face design helps to distribute the load over a larger area during the connection, reducing the stress on the connected parts . 2. Improved vibration resistance: Hex flange face bolts provide better vibration resistance than standard hex bolts, preventing loosening due to vibration . 3. Simplified assembly process: separate washers are not required, reducing the number of assembly steps and saving time and costs. 4. Corrosion resistance: many hexagonal flange face bolts are made of stainless steel or are treated with protective coatings, such as Dacromet, to enhance their corrosion resistance. 5. High load carrying capacity: Due to the flange face design, these bolts are able to withstand higher preload and load carrying capacity .
Scope of
application
1.Automotive: used for the connection of engine components, chassis and suspension systems, as they are able to withstand high loads and vibrations . 2. Industrial sector: widely used in heavy machinery, manufacturing equipment, construction and infrastructure for fixing and connecting various structural elements . 3. chemical industry: suitable for connecting and fixing pipelines, tanks and other equipment, especially in corrosive environments . 4. Construction and bridges: used for connecting construction structural elements such as bridges, pylons, etc., providing stable and secure connections . 5. Machinery and equipment: used to fix machine parts, such as motors, pumps, etc., in machinery manufacturing.
