The DIN 6923 Hex Flange Nut is a high-performance fastening solution engineered to combine the functions of a standard hex nut and a flat washer into a single component. By integrating a wide flange base, these nuts distribute the clamping load over a significantly larger surface area, effectively reducing the risk of material deformation and ensuring a more secure, stable joint in demanding industrial environments.
Manufactured from premium carbon steel and available in various protective finishes, our DIN 6923 nuts are designed for versatility across heavy industry, water treatment, and general manufacturing. Whether you require metric or imperial specifications, these flange nuts provide a streamlined installation process, reducing assembly time and eliminating the need for separate washers in most applications.

Frequently Asked Questions
The DIN 6923 nut features an integrated wide flange that acts as a built-in washer, providing a larger bearing surface to distribute pressure and prevent material damage.
In most cases, no. The flange replaces the standard washer. However, for critical joints requiring maximum surface protection or specific locking torque, a separate locking washer may still be used.
For water treatment or high-moisture environments, we recommend Hot Dip Galvanized (HDG) or Zinc plated finishes to provide superior corrosion resistance.
Yes, we specialize in non-standard products. Please provide us with a technical drawing, photos, or a physical sample, and we will produce it to your exact specifications.
Our standard DIN 6923 nuts are manufactured from high-grade carbon steel to ensure strength and durability for industrial use.
Serrated flanges have small ridges that bite into the mating material during tightening, creating a mechanical lock that resists loosening caused by vibration.
