Spring Washers, also known as split lock washers, are designed to provide a preload and prevent loosening due to vibration and thermal expansion. They exert a spring force between the fastener's head and the substrate, maintaining tension and preventing loosening. These washers are widely used in automotive, construction, and electrical applications to secure bolted joints. By maintaining a constant tension, Spring Washers ensure that fasteners remain tight, preventing failures in dynamic and high-vibration environments. Their simple yet effective design makes them a reliable choice for securing components in various industrial settings.
