Abstract
A fastener head adapter includes a drive portion that can be engaged by a suitable driver, and a mating portion that is configured to mate with a fastener head. The fastener head adapter is attached to a fastener head. The fastener head adapter preferably provides a different type of drive portion than exists on the fastener head. Once the fastener head adapter is attached to the fastener head, the screw may then be turned by using the driver to engage the drive portion of the fastener head adapter and to turn the fastener head adapter, which in turn, turns the screw.
Claims4
A combination screw and screw head adapter comprising:
- the screw comprising:
- a threaded portion on a distal end;
- a head portion on a proximal end opposite the threaded portion, the head portion comprising a first recess having a first configuration for receiving a first driver for turning the head portion;
- and
- a reduced-diameter shaft coupling the threaded portion to the head portion, wherein the reduced-diameter shaft has a diameter less than the diameter of the threaded portion;
- the screw head adapter comprising:
- a drive portion having a second configuration for receiving a second driver for turning the drive portion, wherein the second configuration is different than the first configuration such that the second driver is different than the first driver;
- a mating portion having an extended portion that engages the first recess of the head portion of the screw;
- and
- a plurality of side portions that extend along a height of the head portion of the screw and comprise retaining portions that snap into place below the head portion of the screw to mechanically couple the screw head adapter to the head portion of the screw, wherein when the screw is tightened to a piece the screw is being attached to, the retaining portions are captivated between the fastener head and the piece.
