Abstract

A roof cover fastener may include a cover plate having a planar body with a perimeter. A central aperture may be disposed centrally in the body. A first annular rib may be formed into the body and may encircle the central aperture. A second annular rib may be formed into the body and may encircle the first annular rib. A first channel may separate the first annular rib from the second annular rib. A medial aperture may be disposed in the channel between the first annular rib and the second annular rib. Optionally, the fastener may also include an auger element having a first end and a second end. A head may be coupled to the first end, and a tip may be coupled to the second end. A thread crest with a thread root may extend from the second end towards the first end.
