The invention provides an improved Winged Fastener in which a large threaded nut is movably engaged with the threaded sleeve of the Winged Fastener wherein the nut is movable set in a washer such that the washer is placed against a surface, while the sleeve of the winged bolt is placed in a bore in a first matrix and a second matrix is set around the sleeve of the Winged Bolt. As the nut is turned on the threaded sleeve, the second matrix which is placed around the threaded sleeve is caused to be compressed and radially moved outward toward an inner surface of the first matrix. If the second matrix is of a rigid material, the cylinder of matrix is split longitudinally and the pieces are driven radially outward. The invention also provides a second improved Winged Fastener in which a hole is placed in a wing and a cable or tendon is attached to the wing through the hole. The threaded shaft of the Winged Fastener is placed in a threaded nut which is movably set in a washer such that the washer is placed against a matrix and the shaft and wings of the winged bolt are placed in a bore through the matrix. The opposite end of the cable or tendon is anchored deep in the bore and as the nut is turned around the threaded shaft, the Winged Bolt is retracted into the nut and tension is placed on the cable.
