At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 6796. Conical spring washers (heavy-duty Belleville-type lock washers) for bolted connections. A single coned disc that acts as a high-load spring to maintain bolt tension and compensate for settling/relaxation; far stronger than a split spring washer. Sized to bolt clearance M3-M20.
