Hexagonal Flange Weld Nut

A hexagonal flange weld nut is a type of nut that combines a hexagonal body with an integrated flange for added stability and load distribution, specifically designed to be welded onto a metal surface. This type of nut provides a permanent, secure threaded point that can handle high loads and vibration without loosening, making it ideal for heavy-duty applications in automotive, industrial, and structural settings.

Size: M14*1.5*22

Grade: 10

Material: 10b21

Finish: Black, Heat treatment


Key Features:

  • Hexagonal Shape: Allows easy tightening with standard tools after welding, making it compatible with wrenches and sockets.
  • Integrated Flange: The flange extends outward from the nut body, acting as a built-in washer to distribute pressure across a larger area, which reduces stress on the base material and enhances stability.
  • Weldable Design: Engineered to be permanently welded to a surface, creating a robust, vibration-resistant connection. Some variants may have projections or raised points on the flange specifically designed for welding efficiency.

Advantages of Hexagonal Flange Weld Nuts:

  • Permanent Threaded Attachment: Once welded, the nut provides a permanent threaded connection, making it ideal for applications requiring long-lasting stability.
  • Load Distribution: The flange spreads the load, preventing indentation or damage to the material and enhancing the nut’s strength and resistance to loosening under vibration.
  • Anti-Rotation: The welded flange prevents the nut from rotating, even under high torque or load.

Common Applications:

  • Automotive Industry: Frequently used in vehicle frames, chassis, and body panels to provide secure mounting points, especially in areas subject to vibration and stress.
  • Heavy Machinery: Common in equipment that requires a stable, permanent threaded point that can withstand high loads and vibration.
  • Industrial Fabrication and Metalwork: Used to provide durable threaded attachment points on metal enclosures, frames, and housings.
  • Construction: Suitable for structural connections where a strong, fixed threaded point is required for assembly or maintenance purposes.

Benefits:

  • High Stability: The welded connection and flange design provide a high level of stability, even under heavy load or vibration.
  • Efficient Assembly: The flange design eliminates the need for a separate washer, reducing part count and simplifying assembly.
  • Versatile: Available in various materials, including stainless steel and high-strength alloys, to meet specific environmental and strength requirements.
