Split lock washers, also known as spring lock washers, are designed to help prevent nuts and bolts from loosening due to vibration, shock, or dynamic loads. Featuring a helical split design, these washers create tension when compressed under torque, increasing friction and improving fastener retention in mechanical assemblies.
