Overview
This DIN25201-compliant double self-locking washer is engineered for high-vibration and dynamic load applications where fastener security is critical. It provides a permanent, maintenance-free locking solution by creating a powerful clamping force that prevents nuts and bolts from loosening. Manufactured from high-strength carbon steel and finished with a protective Dacromet coating, this washer delivers both mechanical reliability and long-term corrosion resistance, making it an essential component for demanding industrial assemblies.
Key Features
Double self-locking design for maximum vibration resistance Dacromet finish provides superior corrosion protection compared to standard zinc plating 300HV material grade ensures high strength and durability Eliminates the need for separate lock washers or thread-locking compounds Maintains clamping force under extreme dynamic loads and temperature fluctuations Prevents spontaneous loosening, reducing downtime and safety risks
