A fastener system (22) includes an applicator (24) for engagement by a tool, and a fastener such as a screw (10) with threads (14) in a first hand direction for engaging a workpiece. The applicator and fastener are threaded (23) together in an opposite hand direction to the first hand direction. When torque applied by the tool in the first hand direction exceeds a predefined magnitude the applicator and fastener will begin to unthread thus preventing any further torque from being applied.
