Professional Applications & Engineering Value

These M16 split lock washers are engineered to solve critical vibration-related challenges in industrial applications. The black-oxide steel material provides superior corrosion protection while maintaining the necessary spring tension for effective locking performance. The split lock design creates constant pressure against both the fastener and bearing surface, preventing rotation and maintaining clamp load in machinery, automotive assemblies, and heavy equipment. Meeting DIN 7980 standards ensures precise dimensional control and reliable performance in demanding environments where vibration resistance is essential for operational safety and reduced maintenance costs.
