These screws are different than the other coffin screws in our catalog. These are not like a finial but are more like an umbrella or cap that fits over the surface. This set of four are made of lead and, therefore, are heavy.
Each screw’s cap is 1 1/4 inches wide and projects 3/4 inch from the surface. The embedded screw is one inch long from the base of the cap.
This is a very unusual set.
