For many years, spring washers have been used across numerous industries, including transmission towers erection, railways, automobiles and engineering applications that require a locking action against the rotation of a bolted assembly. Sometimes referred to as disc springs, these parts are highly effective in taking up play, reducing rattle, sustaining tension throughout an assembly, compensating for any expansion or contraction after assembly, absorbing intermittent shock loads and controlling reactions under dynamic loads. Manufactured from premium quality stainless steel, brass copper bronze or aluminum for durability.
