Abstract
A one-piece fastener adapted to be driven into a drilled hole in masonry material. The fastener includes features which define a helical flight causing the fastener to rotate as it is driven in place. The fastener shank is configured to cause abrasion of the pre-drilled hole and is dimensioned such that a radially compressive force acts on the wall of the masonry hole to provide for enhanced retention of the fastener after it is set in place. A radially enlarged shoulder is provided on the fastener adjacent its driving end to tightly engage the entrance end of the masonry hole to provide firm radial support for the driving head and structure which it supports.
