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. Bare finish fasteners have low corrosion resistance and are a good choice for indoor and industrial applications.
- The split in the ring allows it to exert a spring force and grip the bolt or screw, preventing it from turning
- They are easy to install without any additional tools
- They are widely used in automotive applications, machinery, outdoor equipment, and any assembly where the fastener might be subject to motion or vibration that could potentially loosen it
