ITEM NAME   SPRING,HELICAL,TORS
DEFINITION  An open-or close-wound coil spring consisting of one or more helical
             coils, wound from different shapes and types of material and finished
             at the ends, designed to exert pressure in a rotating direction around
             the coil axis. Excludes springs designed for thermal actuation
             (springs in which the torsion forces are counteracted by changes in
             temperature) and SPRING, REINFORCING, HOSE.
