High-Quality Flange Nuts

What is a Flange Nut?

A flange nut is a specialized, heavy-duty fastener that features a wide, integrated flanged base at one end. This unique design acts as a built-in, non-spinning washer, which effectively distributes the pressure of the nut over the part being secured. By eliminating the need to source and install a separate washer, flange nuts significantly streamline the assembly process, reduce overall hardware costs, and decrease the likelihood of the fastener loosening over time.

Available Designs and Mechanical Benefits

To accommodate different structural and mechanical environments, flange nuts are primarily manufactured in two distinct styles, each offering specific functional benefits:

• Flat Flange Nuts: Designed with a smooth bearing face that provides excellent load distribution. They protect the mating surface from damage and ensure a highly secure, flush fit.
• Serrated Flange Nuts: Fabricated with engineered, built-in serrations on the bottom of the flange. During installation, these angled teeth bite directly into the mating surface, creating an exceptional locking mechanism that heavily resists loosening caused by intense vibration or dynamic loads.

Available Materials and Customization

To guarantee maximum holding power and environmental durability, U-Bolt-It manufactures both flat and serrated flange nuts in a wide variety of premium, industrial-grade materials. Whether your heavy-duty assembly requires high-strength carbon steel, lightweight aluminum, or highly corrosion-resistant stainless steel for outdoor exposure, we can supply the exact fasteners required for your project.
