DIN6796 Conical Spring Washers are also called Belleville washer, Disc Washer, Spring Washers and etc.. They are designed for static applications as heavy duty bolting disc washers. Sunzo always has the metric size in stock, we are professional at this standard. They are made from spring steel, steel or other alloys with elastic characteristics, which offer high resistance to axial loads.
Nominal bolt size: Diameter of the screw or bolt suitable for this washer
D: Internal diameter with H14 tolerance
d: External diameter with H14 tolerance
t: Washer thickness with tolerances according to DIN 6796
Ho: Height of the piece
Flattening force: Force in Newtons of the washer when being flattened
