They are about an inch in diameter with the 4 or 5mm bolt hole in the center, you put one above and below the blade then insert everything into the blade grip. The thickness of the blade is a tad bit thinner than the opening in the blade grip and the spacers even out the thickness so you aren't squeezing or pinching down on the blades putting stress on the blade grips. The washers sometimes come in a hard black plastic or metal depending on the blade manufacturer.
Hope this helps,
