The washers are also referred to “belleville” washers or “spring washers”. These pieces are manufactured according to DIN 6796 and they are conical washers made from steel or other alloys with elastic characteristics, which offer high resistance to axial loads.
The special shape (formed like a disc spring) enables the conical spring washer to achieve a high spring effect.
Steel washers are stronger and more wear resistant than zinc-plated steel and stainless steel.
