ABSTRACT:
A fastener with a breakaway and methods of using the same. In one embodiment the fastener is a screw having a head and elongated stem, adapted to be easily manipulated by a user when using the screw as a fastener in a hinge or joint. A means of holding a screw by providing a breakaway tab or non-threaded second portion of the elongated stem which can be used to align and insert the screw into a screw hole in the process of engaging threads in the screw hole with threads of the screw. After engaging the threads in the screw hole, such as after the screw has been essentially completely inserted into the screw hole, the breakaway tab or non-threaded second portion of the elongated stem of the screw may be broken off at a breakaway and discarded.
