What is a flange nut

Flange nut is a versatile fastener commonly known as gasket nut, flower tooth nut, hexagonal flange face nut, flange nut, and more. Whether you're connecting pipes or working with pieces that require added contact surface area, this nut is an excellent choice. Its practical design provides a secure and durable hold that can withstand the demands of various applications. So, if you're looking for a reliable and effective solution for your fastening needs, consider using a flange nut.

A useful type of nut is the flange nut, designed with a wide flange at one end that doubles as a washer. By spreading the pressure of the nut over the part that it fastens, the risk of damage to the part is reduced, while the nut is less likely to become loose due to uneven tightening surfaces. Typically hexagonal in shape, flange nuts are crafted from hardened steel, often plated with zinc to ensure longevity.

In certain cases, the flange and nut are connected and rotate together. The flanges may feature serrations that offer a locking mechanism. These serrations are shaped at an angle to prevent the nut from rotating in the same direction one turns to loosen it. Owing to the serrations, washers cannot be used and they may not be suitable for use on uneven surfaces. The serrations are invaluable in preventing the nut from coming loose due to vibration, thus ensuring that the nut remains securely fastened.

Rotating flange nuts provide added stability to structures while maintaining the quality of the final product, unlike serrated flange nuts. They are particularly useful when joining wood and plastic materials. In some cases, both sides of the nut have serrations, enabling either side to effectively lock into place.

Self-aligning nuts are designed with male spherical flanges that perfectly fit into the female dish washers. This unique design enables the nut to be tightened on surfaces that are not perpendicular to the nut. This means that even if the surface is at an angle or off-axis, the nut can still be tightened securely. This makes self-aligning nuts a great choice for applications where perfect alignment is not possible, but a secure fit is still needed.
