DIN 6796 Cup Washer is a type of conical spring washer used in bolt connections that require high pre-tension forces. This washer distributes the force applied during tightening over a wide surface area, enhancing the tightness of the connection and preventing the bolt from loosening. Its bowl-shaped design provides elastic pressure, which helps to prevent loosening of the fasteners due to external factors such as vibrations or thermal expansion. Typically manufactured from steel or stainless steel, DIN 6796 Belleville washers are commonly used in high-performance and reliability-demanding fields such as machine manufacturing, automotive, and the energy sector.
