Plain/Standard Conicals:

These are the most common bellevilles used in the market to provide a resistance to thermal expansion and contraction.

Serrated Belleville:

Serrated on the top only, near the inner diameter, these spring washers grip the head of a bolt or nut to resist extreme vibrations.

Toothed Periphery Conicals:

These are also called paint cutting serrations, because the outside teeth can cut into the mating surface.
