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. 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.

1. A roof cover fastener that attaches roof materials to lightweight insulating concrete and other roof deck materials, the fastener comprising a. a cover plate, the cover plate comprising: a planar body having a perimeter,a central aperture disposed centrally in the body,a first annular rib formed into the body and encircling the central aperture,a second annular rib formed into the body and encircling the first annular rib,a first channel separating the first annular rib from the second annular rib, wherein the first annular rib and second annular rib extend above the first channel and wherein the first channel has a flat planar first contact surface, the flat planar first contact surface configured to contact a roof material without penetrating the roof material,a first circular shaped medial aperture and a second circular shaped medial aperture disposed in the first channel between the first annular rib and the second annular rib;b. a first auger element, the first auger element comprising: a first end and a second end,a head coupled to the first end,a tip coupled to the second end, anda thread crest with a thread root extending from the second end towards the first end; and wherein the first circular shaped medial aperture and the second circular shaped medial aperture are both configured to receive an auger element as it is driven into the roof material. 2. The fastener of claim 1, wherein the first auger element is secured within the first circular shaped medial aperture and a second auger element is secured within the second circular shaped medial aperture. 3. The fastener of claim 2, wherein the first and the second circular shaped medial apertures are symmetrically positioned relative to each other with the central aperture located in-between the first and the second circular shaped medial apertures. 4. The fastener of claim 1, further comprising a second channel formed into the body of the cover plate, and wherein the second channel encircles the central aperture. 5. The fastener of claim 4, further comprising a third channel encircling the second annular rib, and wherein the first annular rib and second annular rib extend above the third channel. 6. The fastener of claim 1, wherein the medial aperture comprises a second width dimension (W2), wherein the thread root comprises a third width dimension (W3), wherein the thread crest comprises a fourth width dimension (W4), and wherein the fourth width dimension (W4) of the thread crest is at least 1.5 times greater than the third width dimension (W3) of the thread root. 7. The fastener of claim 6, wherein the fourth width dimension (W4) of the thread crest is more than 1.8 times the third width dimension (W3) of the thread root. 8. The fastener of claim 6, wherein the fourth width dimension (W4) of the thread crest is more than 2.0 times the third width dimension (W3) of the thread root. 9. The fastener of claim 1, wherein the fastener has an average withdrawal resistance from cellular concrete of greater than 500 Lbs/Force when three auger elements are used in combination with the cover plate. 10. The fastener of claim 1, wherein the fastener has an average withdrawal resistance from cellular concrete of greater than 600 Lbs/Force when four auger elements are used in combination with the cover plate. 11. The fastener of claim 1, wherein the tip is tapered between 15 and 45 degrees relative to the thread root and thread crest. 12. The fastener of claim 1, wherein the first auger element further comprises a plurality of auger splines located proximate to the first end below the head. 13. The fastener of claim 12, wherein the plurality of auger splines comprise spline ridges positioned adjacent to spline valleys. 14. The fastener of claim 12, wherein the plurality of auger splines comprise spline tapered thread positioned within the auger splines. 15. The fastener of claim 14, wherein the spline tapered thread has a maximum crest width which is a fifth width (W5) which is less than a fourth width (W4) of the thread crest. 16. The fastener of claim 14, wherein the tapered thread becomes flush with a spline ridge as it approaches the top of the auger splines near the head causing a top tapered crest to not protrude further outward than a spline ridge at a distal top of the tapered threading. 17. An improved auger element, the auger element comprising: a. a shank having a first end coupled to a head and a second end having a tip;b. a thread having a thread root and a thread crest, the thread root having a third width (W3) and the thread crest protruding outwardly away from the shank and having a fourth width (W4); andc. a plurality of auger splines positioned along the first end of the shank below the head, the plurality of auger splines comprising spline ridges positioned adjacent to spline valleys and the plurality of auger splines further comprising a tapered thread positioned about the plurality of auger splines, the tapered thread having a maximum fifth width (W5) which is less than the fourth width (W4) of the thread crest and the tapered thread becoming flush with a spline ridge and a top tapered crest. 18. The auger element of claim 17, further comprising an unthreaded upper shank positioned between the head and auger splines. 19. The auger element of claim 18, wherein the unthreaded upper shank is void of auger splines and threading.
