Product Description

Automobile Industry DIN6921 Machine Bolt for High Pressure Applications

Product Description

DIN6921 Hexagon Head Flange Bolt is a type of bolt featuring a hexagon head and a built-in flange. This design combines the user-friendly characteristics of hexagon bolts with the anti-slip fastening advantages offered by flange structures. The integration of these features allows for stable connections to be achieved without the requirement for additional gaskets.

Features

Core Structure

The bolt head is a standard hexagonal shape, compatible with tools such as wrenches, making it easy to quickly tighten and disassemble.
The lower part of the head is integrally formed with a ring-shaped flange surface, some of which have anti slip serrations to enhance the locking effect.
The rod is designed with full or half threads according to the connection requirements to ensure effective engagement with the nut.
Other standards: German DIN 931/933, American ANSI B18.2.1, etc.

Core Strengths

Increase the contact area of the flange surface to evenly distribute pressure and reduce damage to the surface of the connecting parts.
The serrated flange surface can produce a mechanical locking effect, and its anti-vibration and anti-loosening effect far exceeds that of ordinary bolts, making it suitable for dynamic working conditions.
The integrated flange design eliminates the step of separately installing gaskets, simplifies the assembly process, and improves construction efficiency.

Applications

Fasteners are widely utilized across various industries including automobiles, machinery, construction, home appliances, and pipeline engineering. In the automotive sector, they play a critical role in securing chassis and engine components. In machinery, fasteners are essential for connecting the shell and bracket of mechanical equipment. Moreover, fasteners are used for sealing and fastening pipeline flanges in construction projects. They are also pivotal in the assembly of internal structures in household appliances like washing machines and air conditioners.
