Key specifications

Choosing the right option

Choose by internal diameter Di first: it has to suit the bolt or shaft the washer sits on. Then match size (mm) and thickness T to the space you have and the spring force you need. Stacking disc springs in series adds deflection and stacking them in parallel adds force. Check the internal diameter Di against the shaft or housing you are fitting it to.
