1. Descriptions:

flange nut is a type of nut that has an integral flange, or washer-like extension, built into one side of the nut. The flange serves as a washer and provides a larger surface area for distributing the load and preventing the nut from loosening. Here is a description of a flange nut:

1. Design: Flange nuts have a standard nut design with internal threads for mating with a bolt or threaded rod. However, they feature an enlarged, circular flange on one side of the nut. The flange is typically larger in diameter than the nut itself and has a flat or slightly curved surface.

2. Flange Function: The flange of a flange nut serves multiple purposes. Firstly, it acts as a washer, providing a larger load-bearing surface and distributing the pressure or load over a wider area. This helps prevent damage to the material being fastened and reduces the risk of the nut sinking into the surface.

3. Locking Feature: Flange nuts often incorporate a serrated or ribbed underside of the flange. When the nut is tightened, these serrations grip into the surface, creating additional resistance against rotation and preventing the nut from loosening due to vibration or other external forces. This built-in locking feature eliminates the need for separate lock washers or other locking mechanisms.

4. Applications: Flange nuts are commonly used in applications where vibration resistance and secure fastening are critical. They are frequently employed in automotive, machinery, industrial equipment, and construction projects. Flange nuts are particularly useful in applications where there is limited access to the backside of the joint, as they can be tightened from one side while providing stability and preventing rotation.

5. Material and Coatings: Flange nuts are available in various materials, including steel, stainless steel, brass, and nylon. The choice of material depends on the specific application requirements, such as strength, corrosion resistance, or temperature resistance. Additionally, flange nuts can be coated or plated with materials like zinc, nickel, or chrome to enhance their corrosion resistance and appearance.

When using flange nuts, it is important to ensure the correct size and thread compatibility with the mating bolt or threaded rod. The flange side of the nut should be positioned against the surface being fastened, allowing the flange to provide its intended functions of load distribution and locking.

In summary, a flange nut is a type of nut with a built-in flange that acts as a washer and provides a larger load-bearing surface. It offers improved resistance to vibration and helps prevent nut loosening. Flange nuts are commonly used in applications where secure fastening and vibration resistance are required.
