Belleville Washers

Belleville washers come under the spring type washers and are used to apply a flexible pre-load to a bolted joint. They can be used individually or in a stack for increased frictional grip. When these washers are used in a stack, they can either be stacked with a similar orientation or stacked orientation depending on the requirements of the applications. The most important advantage of these washers from ITA Fasteners is that they can support huge loads even in a cramped installation space.
