Abstract
A screw includes a screw head, a threaded shaft, and a force release component connecting the screw head to the threaded shaft. The force release component releases the screw head from the threaded shaft in response to a specified force. The specified force is substantially along a screw axis in-line with the threaded shaft.
Claims15
A screw comprising:
- a screw head;
- a threaded shaft;
- and
- a force release component comprising a screw plunger connected to the screw head that is coaxial with the threaded shaft and inserted into an opening in the threaded shaft and connecting the screw head to the threaded shaft to the screw, wherein the screw plunger is bonded to the threaded shaft with an adhesive, and wherein the plunger extends into the opening shaft a distance less than a length of the threaded shaft, and wherein the screw plunger releases from the threaded shaft in response to a specified force on the screw head, the specified force is substantially along a screw axis in-line with the threaded shaft.

A system comprising:
- a first component;
- a screw comprising a screw head and a threaded shaft;
- a second component secured by the screw to the first component;
- and
- a force release component comprising a screw plunger connected to the screw head that is coaxial with the threaded shaft and inserted into an opening in the threaded shaft and connecting the screw head to the threaded shaft to the screw, wherein the screw plunger is bonded to the threaded shaft with an adhesive, and wherein the plunger extends into the opening a distance less than a length of the threaded shaft, and wherein the screw plunger releases the screw head from the first component in response to a specified force on the screw head, the specified force is substantially along a screw axis,
- wherein a bond strength between the screw head and the threaded shaft is less than a bond strength between the threaded shaft and the first component.

A method comprising:
- providing a first component;
- providing a screw comprising a screw head and a threaded shaft;
- providing a force release component comprising a screw plunger connected to the screw head that is coaxial with the threaded shaft and inserted into an opening in the threaded shaft, the screw plunger connecting the screw head to the threaded shaft to the screw, wherein the screw plunger is bonded to the threaded shaft with an adhesive, and wherein the plunger extends into the opening a distance less than a length of the threaded shaft, and wherein the screw plunger releases the screw head from the first component in response to a specified force on the screw head;
- and
- securing a second component to the first component by securing the screw through an opening in the second component and the threaded shaft into the first component,
- wherein a bond between the threaded shaft and the first component comprises a bonding strength such that, in response to the specified force, the screw head and screw plunger separates from the threaded shaft and breaks a bond between the screw plunger and the threaded shaft while the threaded shaft remains connected to the first component.
