Abstract

A sound dampening fastening element includes a sound dampening body, an anchoring member and a support member. The dampening body is prism-shaped and formed of a resilient material. The anchoring member has a head and a shank with the head and a portion of the shank embedded within the dampening body and the remaining portion of the shank extending outwardly from the dampening body. The support member is partly embedded within the dampening body and the remaining part extends outwardly from the opposite side of the dampening body from which the shank extends. The support member has a shaped configuration with wall sections within the dampening body combining to form an opening through which the shank extends. The diameter of the opening is greater than the diameter of the shank but smaller than the diameter of the head of the anchoring member. The part of the support member extending outwardly from the dampening body includes openings for receiving a belt-like support element and also a threaded opening.
