Structural Features
Features a hexagonal body with an integrated wide flange, often equipped with anti-slip serrations underneath. It contains an internal nylon insert (PA6/PA66) at the top. The flange acts as a built-in washer to increase contact area, while the nylon insert elastically deforms to tightly grip the bolt threads.

Performance Advantages
• Dual Anti-Loosening: Combines serrated flange bite and nylon friction for excellent vibration resistance.
• Uniform Pressure: The wide flange spreads the load, preventing damage to the workpiece surface.
• Reusable: The nylon insert retains its elasticity, allowing for multiple uses without losing locking power.
• Corrosion Resistant: Typically made with a stainless steel body for durability in harsh environments.

Application Scenarios
Essential for reliable fastening in high-vibration environments. Widely used in automotive chassis, electrical cabinets, construction machinery, rail transit, and agricultural equipment.
