DIN 6331 High Strength Hexagon Flange Nuts are fasteners with high load carrying capacity and high stability, especially suitable for applications requiring frequent clamping and unscrewing. These nuts are characterized by a raised edge, which means that no additional washers are required during installation.DIN 6331 hexagonal nuts are usually made of steel with a tensile strength class 10 and are blackened to improve corrosion resistance.

Carbon Steel: Typically used for general applications.

Stainless Steel: For environments where corrosion resistance is required.

Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

High loadbearing capacity: The hexagon flange nut provides a larger support surface and stronger tightening force. Vibration Resistance: The flange nut is designed to prevent loosening due to vibration or rotation. No Washers Required: The flanged design eliminates the need for washers and simplifies installation.

Scope of Application

Heavy Machinery: Suitable for heavy machinery, automotive and construction applications where extreme stability and load bearing capacity is required. Pipe Connections: Commonly used for pipe and flange connections, especially in applications where extra tightening and prevention of loosening is required. Industrial Manufacturing: Used in industrial manufacturing environments where high vibration or high torque is required.
