Spring Lock Washers, also referred to as helical spring washers or split washers, are one of the most commonly used washers in fastening assemblies. Their helical shape creates spring tension that helps prevent loosening due to vibration or torque, making them a reliable alternative to flat washers in many bolted joints.

These washers are available in both hardened and as-formed conditions, depending on the application’s strength and durability requirements. Adfast Component supplies spring lock washers in a variety of metric and imperial sizes, offering multiple material options to suit different industrial needs.
