Abstract

572,218. Bolts and nuts. CROSS, A. T. Jan. 27, 1944, No. 1524. [Class 89 (i)] Bolts are made from circular, or square or other section wire A, coiled to form a stiff spring. The head is formed by making an enlarged coil and either turning up the sides C to form flats for the spanner or flattening the sides of the coil. The nut is forged or machined to engage the turn of the helix, and may be of hexagonal, wing or other form. The bolt may be formed without head and used with a nut on each end.
