Product Description:
Hex flange head bolts DIN6921 are commonly used in automobile
manufacturing to secure engine, chassis, and body components. Their
outstanding strength and corrosion resistance make them ideal for
meeting the rigorous demands of automotive parts.As vehicles are
driven, they inevitably produce vibrations. The hexagonal flange
bolts are designed with a large support area and excellent
anti-loosening properties to guarantee the stability of crucial
connections, such as those within the engine, during this process.
Features:
The fastening is excellent, with the flange surface resembling a
built-in super strong gasket. This design allows for even
distribution of force, reducing deformation and damage to the
connecting parts. It securely fastens together components of
different materials like metal or plastic.
Compared to regular hexagonal bolts, this fastening solution offers
superior anti-loosening performance. The toothed flange bolt, in
particular, provides enhanced effectiveness, ensuring stability
even in high-vibration environments such as car engines.
Various options are available to suit different needs: Level 4.8 is
ideal for smaller applications like home décor; Grade 8.8 is
commonly utilized in automobiles and construction machinery; and
Level 10.9 is capable of withstanding heavy loads.
