Abstract
A fastener including a head having a screw driver or wrench engagement feature. The fastener includes a threaded shank extending from the head. A plurality of voids or scores in the shank spaced from but near the head permit rotational torque on the head in one direction significantly greater than rotational torque in an opposite direction so that rotational torque in an opposite direction causes the head to break off from the shank.
