Overview
This DIN 25201 self-locking washer is engineered for high-performance, vibration-resistant bolted connections in demanding industrial environments. Manufactured from 65Mn carbon steel, it delivers exceptional tensile strength and fatigue resistance. The unique dual-layer, interlocking design creates a powerful spring action that maintains clamp load, preventing loosening under dynamic loads and shock without galling or damaging the mating surfaces. A zinc flake coating provides enhanced corrosion protection, making it suitable for a wide range of operating conditions.
Key Features
DIN 25201 compliant dual-layer self-locking design Constructed from high-strength 65Mn carbon steel Zinc flake finish for superior corrosion resistance Maintains clamp load to prevent vibration-induced loosening Non-marring design protects flange and bolt head surfaces Consistent 0.04-inch thickness for reliable performance
