1. A method of securing a rivet to a plate, the method comprising the steps of:
providing a plate having a plate hole therethrough, the plate having a backside and a frontside opposed thereto;
nonrotatably disposing a rivet through the plate hole, the rivet having an internally threaded rivet hole and being complementary to the plate hole, the rivet having a hat disposed on the backside and a shank extending longitudinally from the hat and outwardly from the frontside of the plate;
inserting the shaft of an externally threaded fastener into the internally threaded rivet hole, the threaded fastener being rotatably disposed in a bore of an elongate driver having a cone at a first end and a heel at a second end opposed thereto, the threaded fastener having a head larger than and juxtaposed with the heel and being larger than the diameter of the bore of the elongate driver; and
axially rotating the threaded fastener to thereby draw the cone of the elongate driver into the rivet hole whereby the cone intercepts a circumference of the rivet hole to deform the rivet about the frontside of the plate.
