Product Description:
DIN6921 Hex Flange Head Bolts
In automobile manufacturing, hexagonal flange bolts are commonly employed to secure engine, chassis, and body components. With their superior strength and corrosion resistance, these bolts are able to meet the strict standards set for automotive parts.
The operational life of a vehicle involves continual vibration. The hexagonal flange bolts, with their broad support area and excellent anti-loosening properties, play a crucial role in maintaining the stability of key components like the engine during driving.
Features:
The fastening is of high quality, with the flange surface resembling a super strong built-in gasket. This feature helps in the even distribution of force, reducing deformation and damage to the connecting parts. It securely fastens parts made of different materials such as metal or plastic.
Compared to standard hexagonal bolts, it offers superior anti-loosening performance. The toothed flange bolt provides even better effectiveness, ensuring stability in high vibration environments like car engines.
There are various options to choose from:
- Grade 4.8 is suitable for smaller applications such as home decoration.
- Grade 8.8 is commonly used in automobiles and construction machinery.
- Grade 10.9 is designed to withstand heavy loads.
