Torsion spring Various Size Length Diameter Assortment High Tension

A torsion spring is a mechanical force storage structure, mostly made of flexible steel. Like the common metal clamp, it can be automatically clamped because there is a torsion spring inside it.
  This type of torsion spring can be used as a power spring to make the torsion bar of tanks and automobiles. And because the torsion bar is small in size and large in torque, it can also be used as a shock absorbing structure for model cars.
