ABSTRACT:
A removable threaded fastener is provided which comprises a head component; an externally threaded 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 torque in a driving engagement with the shank component without an integral torque transfer means. Also provided is a method for removably fastening a work piece using the removable threaded fastener by inserting the fastener through a threaded aperture in the work piece; inserting the tool into the longitudinal opening; applying torque 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; and removing the tool.
