Abstract

1,219,237. Making screws; extruding; selftapping screws. L. SIMONS. 8 April, 1969, No. 17917/69. Headings B3A, B3N and B3P. [Also in Division F2] A screw or a self-tapping screw formed by extruding a blank to form a head and three shank portions side by side, twisting the shank portions together in one angular direction and forming a thread of opposite angular direction. The three shank portions may be separate (Fig. 3, not shown) or be formed as lobes to a central wire (Fig. 5, not shown). In the former ease a plastic or metal wire may be placed between the shank portions before twisting (Fig. 9, not shown). The thread may be formed by rolling. The shank may also be stretched while being twisted.
