Split Lock Washers

Find split lock washers from Olander in an array of materials, finishes, sizes, and other configurations. Also referred to as helical spring lock washers or simply spring lock washers, this special type of washer differs from a flat washer, offering greater protection against vibrations. Designed in a semi-coil shape that gradually rises, resulting in one side being higher than the other side, split washers compress when used with a bolt (or nut) and act as a spring to help distribute the load of the bolt more evenly in an object. They are particularly useful and highly recommended in applications involving machines and equipment that produce vibrations, which can sometimes cause bolts to loosen.
