Abstract
A weld nut for use in securing a fastener to a sheet of supporting material. The weld nut comprises a triangular-shaped plate with truncated vertices. The plate has a mating surface from which are raised first, second and third integral projections. Each of the integral projections has a frusto-conical body with a rounded top and is surrounded by an annular channel to contain the flow of the material forming the projection when the nut is welded to the supporting material. Each channel preferably intersects an adjacent truncated end to permit the formation of an external fillet.
