Professional Applications & Engineering Value
These M20 split lock washers deliver critical vibration-resistant fastening solutions for industrial machinery, automotive assemblies, and heavy equipment applications. The curved spring design creates continuous radial pressure that prevents loosening under cyclic loading conditions, while the black-oxide steel construction provides excellent corrosion resistance without compromising the material's inherent strength. Engineered to DIN 128A specifications, these washers maintain consistent spring force and dimensional accuracy, ensuring reliable performance in high-vibration environments where fastener security is paramount. The combination of Rockwell C44 hardness and precise metric dimensions makes them ideal for maintenance-critical applications requiring durable, long-lasting locking solutions.
