Product Description:
DIN6921 Hex Flange Head Bolts
In automobile manufacturing, hexagonal flange bolts are used to fix
engine, chassis, and body components. Their high strength and
corrosion resistance meet the stringent requirements of automotive
parts.During the driving process, the car will generate vibration.
The large support area and good anti-loosening performance of the
hexagonal flange bolts can ensure the stability of the connection
of key components such as the engine.
Features:
The fastening is of superior quality, with the flange surface
resembling a built-in highly durable gasket. This unique design
allows for the even distribution of force, reducing deformation and
potential damage to connected parts. It securely fastens parts made
of different materials like metal or plastic.
When compared to traditional hexagonal bolts, this product offers
enhanced resistance to loosening. Notably, toothed flange bolts
deliver an even stronger hold, making them ideal for maintaining
stability in high-vibration environments such as car engines.
There are various options to choose from: Level 4.8 is suitable for
smaller applications like home decor projects; Grade 8.8 is
commonly used in automobiles and construction machinery; Level 10.9
is designed to withstand heavy loads.
