Serrated Flange Lock Nuts, Zinc Plated, are designed to provide secure fastening with increased resistance to loosening. The serrated flange eliminates the need for washers by distributing pressure over a larger surface area, while the serrations bite into the material, preventing slippage. The zinc plating provides moderate corrosion protection, making these nuts ideal for automotive, machinery, and construction applications exposed to vibration. Applications: [ Automotive ] Ideal for use in vehicles where vibration resistance is crucial. [ Machinery ] Suitable for fastening components in industrial equipment. [ Construction ] Perfect for structural assemblies requiring secure, vibration-resistant fasteners.
