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.

A screw, comprising:
- a screw head, comprising:
- a first surface having a driver slot thereon, and a second surface, wherein the second surface of the screw head faces away from
- the first surface;
- 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 threaded first portion is mechanically and physically coupled to the second surface of the screw head,
- wherein the physical coupling between the second surface of the screw head and the proximal end of the threaded first portion is not a breakaway,
- wherein the breakaway releasably couples the non-threaded second portion to the distal end of the threaded first portion,
- wherein a diameter of the non-threaded second portion is smaller than a diameter of the threaded first portion of the elongated stem, and
- wherein the breakaway has a diameter sized so that the non-threaded second portion is directly decoupled from the threaded first portion of the elongated stem at the breakaway by hand, without the use of a tool.
A releasably coupled screw and extension, comprising:
- a screw, having a screw head, 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 threaded first portion is mechanically and physically coupled to a second surface of the screw head so that it is not releasably coupled to the second surface of the screw head,
- wherein the physical coupling between the second surface of the screw head and the proximal end of the threaded first portion is not a breakaway,
- wherein the breakaway releasably couples the non-threaded second portion to the distal end of the threaded first portion, and
- wherein a length of the non-threaded second portion is greater than or equal to a length of the threaded first portion, resulting in a user having greater leverage to break off and discard the non-threaded second portion at the breakaway.
An apparatus, comprising:
- a screw, having a screw head, 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 the screw is adapted to be manipulated by hand by a user without the use of a tool,
- wherein the physical coupling between the second surface of the screw head and the proximal end of the threaded first portion is not a breakaway,
- wherein the breakaway releasably couples the non-threaded second portion to the distal end of the threaded first portion,
- wherein the breakaway releasably couples the non-threaded second portion to the distal end of the threaded first portion,
- wherein at least the distal end of the non-threaded second portion extends out of a threaded channel of a hinge,
- enabling the screw to be directly pulled into the threaded channel by hand, by a user, without the use of a tool.
A screw, comprising:
- a screw, having a screw head, 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 threaded first portion is mechanically and physically coupled to a second surface of the screw head so that it is not releasably coupled to the second surface of the screw head,
- wherein the screw is adapted to be manipulated by hand by an user without the use of a tool,
- wherein the physical coupling between the second surface of the screw head and the proximal end of the threaded first portion is not a breakaway,
- wherein the breakaway releasably couples the non-threaded second portion to the distal end of the threaded first portion,
- wherein at least the distal end of the non-threaded second portion extends out of a threaded channel of a hinge,
- enabling the screw to be aligned by manipulating the non-threaded second portion directly by hand by a user without the use of a tool.
A screw, comprising:
- a screw, having a screw head, 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 threaded first portion is mechanically and physically coupled to a second surface of the screw head so that it is not releasably coupled to the second surface of the screw head,
- wherein the physical coupling between the second surface of the screw head and the proximal end of the threaded first portion is not a breakaway,
- wherein the breakaway releasably couples the non-threaded second portion to the distal end of the threaded first portion,
- wherein the diameter of the breakaway is less than or equal to 0.015 in.,
