Descrizione di prodotto
Class 4.8-12.9 DIN6921 DINEN1665S Hexagon Head Flange Bolt
Product Description

The DIN6921 DINEN1665S Hexagon Head Flange bolt is a specific type of bolt that features a hexagon head along with an integrated flange. This design combines the user-friendly aspects of hexagon bolts with the secure fastening benefits provided by flange structures. As a result, it enables stable connections to be established without the requirement of additional gaskets.

By incorporating the flange, this bolt design can help prevent slippage during fastening, making it particularly suitable for applications where a high level of security is necessary. The combination of the hexagon head and flange creates a versatile fastening solution that offers both ease of use and effective connection stability.

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 include 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

Typical application areas include a wide range of industries, such as automobiles, machinery, construction, home appliances, and pipeline engineering. For instance, self-tapping screws are commonly utilized for tasks like securing automotive chassis and engine components, forming connections between the shell and bracket of mechanical equipment, sealing and fastening pipeline flanges, and assembling internal structures within household appliances such as washing machines and air conditioners.
