Spring washers are specially designed ring-shaped components, typically split or coiled, that provide tension to help prevent fasteners from loosening under vibration and dynamic loads. By maintaining continuous pressure between the fastener and the surface, they enhance grip and improve joint reliability. These washers are effective in absorbing shock, vibration, and fluctuating stresses, making them ideal for demanding applications. Available in various forms such as split, conical, and wave designs, spring washers are widely used in machinery, automotive systems, and structural assemblies where secure and stable fastening is essential.
