Integrated Flange Design
The built-in flange acts as a washer, increasing the bearing surface and reducing pressure on the connected parts. It helps prevent surface damage and eliminates the need for a separate washer in many applications.

Product Overview
Product Application
DIN 6923 Hexagon Flange Nut is a metric flange nut standard featuring an integrated circular flange at the base of the hexagonal nut. The built-in flange works as a washer, increasing the bearing surface and improving load distribution during tightening. It is widely used in automotive, machinery, equipment assembly, and structural fastening applications where installation efficiency and surface protection are required.
Available in plain flange and serrated flange designs, DIN 6923 nuts provide reliable fastening solutions for both general assembly and vibration-resistant applications.
Draw
Specification
DIN 6923 vs Standard Hex Nut (DIN 934)
- Larger Bearing Surface
DIN 6923 includes an integrated flange, while DIN 934 requires a separate washer for similar load distribution. - Faster Assembly
One-piece flange design reduces installation steps. - Better Surface Protection
The flange helps prevent direct contact damage between the nut and the workpiece. - Higher Vibration Resistance (Serrated Type)
The serrated flange provides additional locking performance compared with standard hex nuts.
Product Advantages
Faster & More Efficient Assembly
The one-piece nut-and-washer design reduces the number of components, simplifies installation, and improves assembly efficiency for high-volume production.
Improved Joint Stability
The enlarged contact area provides more uniform load distribution, while serrated flange versions offer enhanced resistance against loosening in vibration environments.
Common Questions
What is DIN 6923 flange nut?
DIN 6923 is a hexagon nut with an integrated flange at the bottom. The flange works as a built-in washer to increase the bearing surface and improve fastening performance.
What is the difference between DIN 6923 and DIN 934?
The main difference is the flange design. DIN 6923 has a built-in washer flange, while DIN 934 is a standard hex nut requiring a separate washer for similar applications.
What is the difference between plain and serrated DIN 6923 nuts?
Plain flange nuts provide better surface protection, while serrated flange nuts provide increased resistance against vibration loosening.
Are DIN 6923 and ISO 4161 interchangeable?
DIN 6923 is closely related to ISO 4161. However, dimensional requirements should always be checked before direct replacement.
