Overview
The DIN 25201 Double Lock Washer is engineered for high-performance, vibration-resistant fastening in critical industrial assemblies. Manufactured to the precise DIN standard, this washer features a unique double-lobed design that provides two independent locking points, creating a more secure and reliable connection than standard single-lobed lock washers. It is an essential component for preventing bolt and nut loosening under dynamic loads, thermal cycling, and severe vibration.
Key Features
Constructed from 65Mn carbon steel for exceptional tensile strength and durability. Dacromet surface finish offers outstanding corrosion resistance, protecting against rust and environmental degradation. Double-lobed design ensures two-point contact for superior locking force and vibration resistance. Precision-engineered to DIN 25201 specifications for guaranteed dimensional accuracy and interchangeability. Ideal for use in high-stress applications where fastener security is paramount.
