Spring Washers, also known as lock washers, provide a circular bearing surface with offset split ends which help bite into the mating material to provide a locking feature when tightened beneath a nut. It is round with a hole in the center and can be used where loosening from vibration is a concern. Lock washers are commonly used in any application using a bolt where two pieces are being drawn together.
