Overview
This DIN 25201 double lock washer is engineered to provide a secure, vibration-resistant fastening solution for industrial machinery and equipment. Manufactured from high-strength 65Mn carbon steel, it is designed to prevent the loosening of components on shafts and axles under dynamic loads and harsh operating conditions. The application of a specialized zinc flake coating significantly enhances its corrosion resistance, ensuring long-term reliability and durability. Supplied in a convenient package quantity of 100, this washer is an essential component for maintenance, assembly, and repair operations where fastener security is critical.
Key Features
Constructed from 65Mn carbon steel for high tensile strength and load-bearing capacity Double-lobed, self-locking design creates a persistent spring force against the nut and bearing surface Zinc flake coating provides superior corrosion protection compared to standard zinc plating Effective prevention of fastener loosening caused by vibration, shock, and thermal cycling Precision-machined bore ensures a consistent and accurate fit on standard shaft sizes
