Helical compression spring

A single cylindrical helical compression spring made from smooth round steel wire, shown upright in side view or slight perspective with a straight central axis and an open hollow center. The spring has a constant coil diameter from top to bottom, evenly spaced close-coiled helical turns with open pitch between the active coils, and a circular wire cross section. Both ends have squared terminal coils that are flattened or ground flat, forming flat circular end turns aligned on the same axis so the spring can stand upright under axial compression. The surface is smooth metallic gray steel, rendered with clean technical or engineering-diagram detail at its uncompressed free-standing length.
