Abstract

1,212,315. Making lock-nuts; forging; welding by pressure. MODULUS CORP. 14 April, 1969, No. 19061/69. Headings B3A, B3H and B3R. [Also in Division F2] A method of making a lock-nut from a metal nut body comprises forming the body into a shape having opposed top and bottom faces and connecting side faces of polygonal periphery, plastically forming a group of flute portions inclined downwardly and outwardly from the top face along a group of side faces, forming a threaded bore in the body, and deforming a group of upper wall portions of the body and the bore inwardly to provide locking thread portions. The inward deformation is performed by a tool T 1 having a forkshaped construction and whose tines define an included angle which is slightly greater than that of the corresponding fluted portions. A projection weld nut 40, having a square periphery, is formed with weld projections 49 and a locating collar 48, which is engaged in an aperture in a workpiece W supported on a lower welding head H 2 . An upper head H 1 presses down on the nut to cause electric current to flow through'the projections thereby welding them to the workpiece. The top planar face of the nut ensures good electrical engagement with the head.
