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.
Claims10
A wedge-type fastener comprising:
- a main body portion having a first internally threaded interior section and a second smooth walled interior section;
- a screw member having external threads adapted to engage and mate with the threaded interior section of said body portion, said screw member being mounted within said body portion and movable from a first position disposed in said smooth walled section to a second position threadably engaging said threaded interior section;
- a pair of spaced wire members fixedly mounted at one end in said screw member;
- a spacer loosely disposed between said wire members movable between a first position totally contained within and between said wire members when said screw member is in said first position and to a second position forcing said wire members apart and extending out of the end of said wire members remote from the ends thereof mounted to said screw member when said screw member moves to said second position;
- and
- an end cap having said wire members extending therethrough encircling both said wire members and said body member and fixedly secured to said body member.
