Περιγραφή προϊόντων
Class 4.8-12.9 DIN6921 Hexagon Head Flange Bolt
Product Description

DIN6921 Hexagon Head Flange bolt is a type of hexagon head bolt with a built-in flange. It combines the easy operation characteristics of hexagon bolts with the anti-slip fastening advantages of flange structures. This design allows for stable connections without the need 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

These products are commonly applied across diverse industries, including automobiles, machinery, construction, home appliances, and pipeline engineering.

For instance, they play a crucial role in securing automotive chassis and engine components, facilitating the connection between the shell and bracket in mechanical equipment, ensuring the sealing and fastening of pipeline flanges, as well as aiding in the assembly of internal structures within household appliances like washing machines and air conditioners.
