SS 304/304L/316/316L/321/321H Spring Washers are fitted with threaded fasteners to maintain pressure within a bolted joint and support secure assembly during operation. The spring profile of the washer creates an elastic loading effect between the nut or bolt head and the mating surface, helping accommodate minor movement and vibration within the connection. The availability of different stainless steel grades allows the washer material to be selected according to the surrounding environment and application requirements.
