Abstract: An apparatus to produce a self-piercing and clinch nut includes a first forging die assembly, a second forging die assembly, a third forging die assembly, a transfer mechanism, and a controller. The first forging die assembly subjects a blank to first processing. The second forging die assembly is adjacent to the first forging die assembly, and subjects the blank, which has undergone the first processing in the first forging die assembly, to second processing. The third forging die assembly is adjacent to the second forging die assembly, and subjects the blank, which has undergone the second processing in the second forging die assembly, to third processing. The transfer mechanism transfers the blank between two adjacent forging die assemblies among the first to third forging die assemblies. The controller controls operations of the first to third forging die assemblies and the transfer mechanism.

Abstract: An apparatus and method are described for attaching threaded fasteners to a workpiece, including applications where the workpiece has a first side and a second side, where the second side may be blind. The apparatus is a threaded insert for inserting in a polygonally-shaped hole in a work piece. Upon activation by an installation tool, the radius corners of the insert expand and fill the hole corners providing resistance to spinning in the workpiece. At least one of the sides of the insert has a split extending axially along the side, which increases the load bearing area of the secondary flange formed on the second side.

Abstract: A Tee nut and method of manufacture is provided which T-nut includes a flange and a hollow barrel extending from the flange. The flange is general circular and has a pair of pawls extending upwardly therefrom, each of which terminates in teeth for engaging a base member. The barrel has an end portion proximal to the flange and a distal end portion. The proximal end portion has internal female threads and the distal end portion has a smooth unthreaded inner surface. The wall thickness of the distal end portion is thinner than the wall thickness of the proximal end portion, and the outer wall diameter is essentially constant for the length of the barrel.The barrel is formed first as an elongate member extending from a strip of material initially having a constant inner diameter and an outer diameter of the proximal portion greater than the outer diameter of the distal portion, with the distal portion having a wall thickness thinner than the wall thickness of the proximal portion. The outer diameter of the distal portion is increased to the same diameter as the outer diameter of the proximal portion while maintaining the same wall thicknesses of both the distal and proximal portions. The internal surface of the proximal portion is threaded with threads terminating at the distal portion and having a lead angle of at least about 80.degree..The terminal end surface of the distal portion is essentially planar and parallel to a flange.
