Belleville washers also called conical spring washers, they are designed for use for bolt/nut assemblies. They offer high axial elasticity to compensate for loosening of the screwed connection due to severe shock or the movement of bolt due to thermal expansion and contraction. Use with high-strength bolts in the strength classes 8.8-10.9.
