Flange Nuts are high-strength fastening components designed with an integrated circular base (flange) that functions like a built-in washer. This design helps distribute clamping force evenly across the surface, preventing damage to the mating material and eliminating the need for separate washers in many assemblies.
These nuts are widely used in industrial, automotive, and structural applications where strong load distribution, vibration resistance, and assembly efficiency are required.
