Abstract
A fastening element assembly includes a fastening element having a head and an axially extending shank, a ring-shaped elastic member laterally enclosing at least an axial part of the shank, and a washer located on the shank between the elastic member and the head. The elastic member can be in contact with the surface of the shank or spaced radially outwardly from it. When using the assembly to attach an object to a support material, an opening or hole is formed in the object with the opening having a diameter approximately the same size as the outside diameter of the elastic member. The fastening element assembly is driven through the opening in the object into the support material so that the elastic member seats in the opening and spaces the shank from the object. Any transverse forces acting on the object are damped by the elastic member before they reach the shank.
