Premium Flange Nut: Enhanced Stability and Locking Performance
A flange nut (also known as a collar nut) is a specialized hexagon nut with a wide flange at one end that serves as an integrated, non-rotating washer. At [Your Brand Name], our DIN 6923 flange nuts are designed to increase the bearing surface of the nut, distributing the clamping pressure over a wider area and protecting the mating part’s surface.
Serrated vs. Smooth Flange Nuts
We provide two primary types of flange nuts to meet different engineering needs:
- Serrated Flange Nut: Features a notched surface on the flange. These serrations dig into the material surface, providing excellent anti-vibration and locking properties, making them ideal for automotive and industrial machinery.
- Smooth Flange Nut: A flat, non-serrated surface used when surface marring must be avoided while still benefiting from the load-distribution of the flange.
Materials, Standards, and Grade 8/10 Performance
Our manufacturing process adheres to strict ISO 9001 quality controls. We offer:
- Stainless Steel Flange Nuts: Utilizing SS304 and SS316 for superior rust resistance in solar racking and marine applications.
- High-Strength Carbon Steel: Our Class 8 and Class 10 flange nuts are heat-treated to ensure they can withstand high torque requirements in structural assemblies.
