Abstract
Abstract A fastener is provided which comprises a head component; a barbed shank component; and a resilient linking means connecting the head and shank components. The fastener has a longitudinal opening adapted to receive a tool for the application of force in a driving engagement with the shank component. Also provided is a method of fastening a plate member to an internally ribbed work piece using this fastener by engaging the fastener with the ribbed aperture in the work piece; inserting the tool into the longitudinal opening; and applying force to the shank component sufficient to cause axial displacement of the shank component against the resilient biasing of the linking means to maintain the head and shank components in axial tension.
