Abstract
A clinch-in fastener with a cylindrical body having a top, a bottom, sides and an axial internal bore. The fastener has a single shank at the bottom end of the body having a top surface orthogonal to the bore and a chamfer tapering to the bottom of the body. The top surface of the shank is adapted for receiving the cold flow of material surrounding a receiving hole of a workpiece. The shank may have a plurality of notches in its outermost edge that extend through both the top surface of the shank and the chamfer. The bore of the fastener extends completely through the fastener body from top to bottom and may be threaded. A fastener installation system having a tool with means for affixation to a rotary and vertically reciprocal element of an industrial machine. The tip of the tool has a distal end face with at least one arcuate displacer adapted for deforming a workpiece as the tool rotates and is pressed against the workpiece. A bore within the tip holds a fastener installed by the tool. The displacer is vertically and radially tapered along an arcuate ridge centered about the axial bore. The width of the displacer is also tapered to a point.
