Product Description:
DIN6921 Hex Flange Head Bolts
In automobile manufacturing, hexagonal flange bolts play a critical role in securing engine, chassis, and body components. Their exceptional strength and resistance to corrosion make them well-suited to meet the rigorous demands of automotive parts.
As a vehicle is in motion, it inevitably produces vibrations. The hexagonal flange bolts, with their generous support area and superior anti-loosening capabilities, guarantee the stability of vital connections like the engine components.
Features:
The fastening is very good, and the flange surface is like a built-in super strong gasket, which can evenly distribute the force, reduce the deformation and damage of the connecting parts, and firmly fasten the connecting parts of different materials such as metal or plastic.
Compared to ordinary hexagonal bolts, it has better anti loosening performance, and the toothed flange bolt has better effect, which can maintain stability in high vibration places such as car engines.
Multiple options available:
- Level 4.8 is suitable for small occasions such as home decor;
- Grade 8.8 is commonly found in automobiles and construction machinery;
- Level 10.9 can withstand large loads.
