Flange Nut
Flange nuts are named for their unique design, which includes a wide, flat base or flange that extends from the nut body. The flange provides a larger surface area than a standard hex nut, which helps to distribute pressure and prevent damage to the surface being fastened. Flange nuts are typically made from durable materials such as stainless steel or carbon steel, and are available in a range of sizes to fit various bolt diameters. They come in standard and metric sizes and are also available in various finishes such as black oxide, zinc plating, and more.
