Patent attributes
The present screw anchor advantageously has two fins radially extending from the body of the screw anchor, where the fins additionally extend above the top end of the body. This unique fin design permits the user to drive the screw anchor into the worn screw hole within a wood substrate so that the screw anchor is substantially flush or recessed within the worn screw hole. When the fins are aligned with the grain of the wood, the fins split the wood at the grain and prevent rotation of the screw anchor. Because the screw anchor is flush or recessed, the anchor does not interfere with the installation of hardware overtop the anchor, such as a hinge. Furthermore, the original screw, such as in the case of a door hinge, can be reused to create an invisible repair.
