Flange Nut

SKU :

Flange Nut is a type of nut that has a wide flange or circular base at one end. The flange provides a larger bearing surface that helps distribute the load and reduce the chance of damage to the surface being fastened. Flange nuts are commonly used in automotive, construction, and industrial applications where vibration and movement are present.

These nuts are typically made from materials such as steel, stainless steel, and brass, and are available in a variety of sizes and thread pitches to fit different bolts and screws. Flange nuts are designed to be tightened with a wrench or pliers, and their flange can also act as a lock washer to prevent loosening due to vibration.

Flange nuts are commonly used in applications where a standard nut may not provide enough support or stability, such as in machinery and equipment that undergoes constant movement or vibration. They are also used in automotive and construction applications, such as securing wheels and bolts on vehicles, or attaching structural components together. Additionally, flange nuts are used in plumbing and electrical applications, where the larger surface area of the flange helps to distribute the load and reduce the risk of damage to the material being fastened.


Flange nuts are specialized types of hex nuts with a wide circular flange at one end. The flange acts as a built-in washer, providing a larger surface area for distributing the load and reducing the risk of the nut loosening.

The following are some of the key properties of flange nuts:

  1. Corrosion resistance: Flange nuts are often made of materials with high corrosion resistance, such as stainless steel or zinc-coated steel, to ensure long-lasting performance in harsh environments.

  2. High strength: Flange nuts are designed to withstand high levels of stress and tension, making them suitable for use in heavy-duty applications.

  3. Increased surface area: The wide flange of a flange nut increases the surface area in contact with the material being fastened, reducing the risk of damage or deformation.

  4. Easy to install: The flange on the nut eliminates the need for a separate washer, simplifying the installation process and reducing the number of components required.

Overall, flange nuts are a versatile and reliable type of fastener that offer improved load distribution, corrosion resistance, and ease of installation.
