Name the device, usually threaded, that displaces the material around a mounting hole when pressed into a properly sized drilled or punched hole. This pressing or squeezing process causes the displaced sheet material to cold flow into a specially designed annular recess in the shank or pilot of the fastener. A serrated clinching ring, knurl, ribs, or hex head prevents the fastener from rotating in the metal when tightening torque is applied to the mating screw or nut.
