Lock nuts with flange in accordance with the DIN 6926 standard are reliable fasteners that provide secure and stable fastening of screw connections. The flange on the nut spreads the load and contributes to increased stability. The nylon ring creates a locking effect to avoid loosening under vibration. The electro-zinc plated surface gives limited corrosion protection. Lock nuts of this type are typically used in construction, machine assembly and other industrial applications where reliable fastening is required.
