ABSTRACT:
A wedge-type low profile fastener is disclosed which is adapted to be inserted into aligned apertures in a pair of abutting surfaces. A hex head is provided on the fastener which is engageable by a tool to rotate the same. Such rotation moves a screw having a pair of spaced wires coupled thereto with a spreader between the wires. As the screw is moved, the wires move along the spreader wedging the spreader between the wires. This moves the wires outwardly against the non-accessible surfaces of the apertures thereby holding the fastener secure in the apertures until the wedging action is removed. The fastener presents a low profile so that the hex head does not stick out too far while retaining a predetermined grip range for the wires.
