ABSTRACT:
A nail 10 for securing vinyl siding 26 to wall sheathing 28 by inserting a pointed end 20 of the nail 10 through a center of a nail slot 30 provided in an edge of the siding 26. A frusto-conical tapered formed bushing 12 proved on a shaft 14 of the nail 10 adjacent to and spaced apart from a head 16 of the nail 10 so that the nail slot 30 of the siding 26 can be popped into the space between the head 10 and the bushing 12 before the nail 10 is driven fully into a wall sheath 28. A smaller flat face 18 of the bushing 12 facing a pointed end 20 of the shaft 14 and a larger flat face 22 facing the head 16. The larger flat face 22 of the tapered formed bushing 12 being either parallel with or at an acute angle to a lower surface 24 of the head 16.
