DIN6923 Carbon Steel Hex Flange Nut
DIN6923 Carbon Steel Hex Flange Nut
The DIN6923 Carbon Steel Hex Flange Nut is a widely used high-performance fastening component designed for stable, vibration-resistant mechanical connections. As a core part of modern industrial fasteners, the DIN6923 hex flange nut integrates a built-in flange base that distributes load evenly while improving tightening stability.
Manufactured from high-strength carbon steel and produced according to DIN6923 standards, this nut is commonly paired with hex head bolt, DIN933 bolt, and various metric bolt systems. It is extensively used in machinery, automotive, construction, and OEM assembly applications where reliability and efficiency are required.
Flybear supplies precision-engineered OEM fasteners designed for global industrial applications with consistent quality and stable performance.

Product Overview
The DIN6923 Carbon Steel Hex Flange Nut features an integrated flange surface that acts like a built-in washer. This design increases the bearing surface and reduces localized stress on connected parts.
Compared with standard hex nuts, the flange structure improves assembly efficiency by eliminating the need for additional flat washers in many applications. It also helps maintain preload stability under vibration conditions.
The carbon steel construction provides excellent mechanical strength, making this DIN6923 flange nut suitable for medium to heavy-duty fastening systems. It is widely used in structural assemblies, machinery equipment, and automotive systems requiring reliable torque retention.
