Abstract
A panel extruding nut for use with a thread forming screw and adapted to be mechanically secured to a flat sheet basal member, the nut including a body having opposed flat surfaces and opposed coaxial first and second bores, the first bore having a diameter slightly larger than the minor diameter of the screw thread, the second bore having a diameter which, together with two extruded or drawn thicknesses of the basal member, is substantially equal to the diameter of the first bore. A punch is used to pierce the basal member and to extrude and shape an integral neck into the second bore which mechanically secures the panel extruding nut. The neck and the panel extruding nut are then threaded by the thread forming screw.
