Disc Spring Washers DIN6796
Conical spring washers are designed as heavy duty bolting spring washers, and have been specially developed for high-strength bolts of grades 8.8-10.9. The washers are confirmed to DIN6796 in 1987, and are designed for high demands on the protection of bolt joints. When the load washer is flattened, a highly progressive load increase occurs at the end of the spring deflection and has been indicated as double the calculated value.
