European Standard Washer
The European Standard Washer (EN 14399-compliant) is a high-performance fastening component designed for industrial and automotive applications. It ensures load distribution, vibration resistance, and joint stability while complying with EU mechanical engineering standards. Made from high-grade stainless steel, the washer combines durability, corrosion resistance, and precision performance for critical bolted joints in machinery, vehicles, and offshore structures.
Application
The washer is suitable for construction machinery, automotive suspension systems, wind turbine bolted joints, railway fasteners, and CNC equipment alignment. Its high-strength design and corrosion resistance make it ideal for both industrial and offshore environments.
