Fastening Metal Pieces Together Hex Head Bolt with Flange Head OEM

Product Description:

The DIN6921 Hexagon Head Flange bolt is a specific type of hexagon head bolt that features an integrated flange. This design merges the user-friendly properties of hexagon bolts with the secure fastening benefits of flange structures. Consequently, stable connections can be established without the necessity for extra gaskets.

The integration of the flange in the bolt enhances its anti-slip capabilities, making it a reliable choice for various applications requiring robust connections. By eliminating the need for additional gaskets, the DIN6921 Hexagon Head Flange bolt simplifies the assembly process and offers a cost-effective solution for fastening needs.

Features:

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.

1. Increase the contact area of the flange surface to evenly distribute pressure and reduce damage to the surface of the connecting parts.

2. 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.

3. The integrated flange design eliminates the step of separately installing gaskets, simplifies the assembly process, and improves construction efficiency.
