Spring Lock Washers, known as split lock washers, are engineered to provide a more uniform load distribution. Ideal for situations where potential loosening from corrosion or vibration is a concern. Lock washers provide a locking spring action and are used to prevent nuts and bolts from coming loose from vibrations. They have split ends that help lock into the mating material, thus providing a locking feature when tightened beneath a nut. The zinc coating applied serves as a protective barrier against corrosion resistance.
- The Zinc coating applied serves as a protective barrier against moderate corrosion resistance
- Yellow zinc fasteners are three times more corrosion resistant than regular zinc
- The split in the ring allows it to exert a spring force and grip the bolt or screw, preventing it from turning
