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.
