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.
Claims10
A screw, comprising:
- a screw head;
- and
- an elongated stem, comprising:
- a threaded first portion and a non-threaded second portion extending from the distal end of the threaded first portion and a breakaway therebetween,
- wherein a proximal end of the breakaway is co-extensive with a distal end of the threaded first portion and a distal end of the breakaway is co-extensive with a proximal end of the non-threaded second portion,
- wherein a diameter of the proximal end of the breakaway is less than a diameter of the distal end of the breakaway, so that the non-threaded second portion and the breakaway decouples cleanly from the threaded first portion when a user applies a torsional or out-of-plane bending force by hand sufficient to decouple the threaded first portion from the non-threaded second portion, without the use of a tool.
