Product Description

Product Description:

DIN6921 Hex Flange Head Bolts In automobile manufacturing, hexagonal flange bolts are used to fix engine, chassis, and body components, and 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 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.
