DIN6921 Hex Flange Head Bolts
In automobile manufacturing, hexagonal flange bolts are commonly employed to secure engine, chassis, and body components. Their exceptional strength and resistance to corrosion make them well-suited to meet the demanding specifications of automotive parts.
The operation of a vehicle typically involves various levels of vibration. The hexagonal flange bolts, with their generous support area and excellent anti-loosening characteristics, play a crucial role in maintaining the stability of critical components like the engine during the driving process.
| | |
The fastening of the flange surface is very reliable, as it functions like a super strong gasket that is integrated within it. This feature allows for even distribution of force, minimizing deformation and damage to the connecting parts. It effectively secures parts made of different materials such as metal or plastic.
Unlike standard hexagonal bolts, this type offers superior resistance to loosening. Toothed flange bolts, in particular, excel in maintaining stability in high-vibration environments like car engines. Various grades are available to suit different needs: Grade 4.8 is ideal for smaller applications such as home decor; Grade 8.8 is commonly used in automobiles and construction machinery; Grade 10.9 is designed to withstand heavy loads.
