Flange Nuts

A flange nut is a nut with an integrated circular or hexagonal flange washer, typically used in applications where even pressure distribution and secure fastening are required. The flange design increases the contact surface, reducing part damage, especially in vibration-prone or dynamic load environments, such as in automotive, construction, and machinery applications. Flange nuts are usually made from carbon steel, stainless steel, and other materials, with various surface treatments like galvanization or oxidation for enhanced corrosion resistance.
