The fastener body has a generally cylindrical configuration and includes an enlarged head adjacent one end thereof, an intermediate shank portion, and a nose portion adjacent the other end thereof. The nose portion engage the buckle sleeve, and during installation causes the buckle of the buckle sleeve to form prior to workpiece contact by the interaction between the nose portion of the fastener and the leading edge of the buckle sleeve. The sleeve buckles the intersection between a trailing section and the largest inner diameter at the end of a tapered interior section.
