A helical spring is a coiled mechanical device which stores and releases energy to absorb impacts or shock and to resist either compression or pulling forces between objects. It is typically a cylinder shaped spring with any number of progressive coils. The wires used to manufacture helical springs are generally specially tempered after their construction to give the spring its compression characteristics. The tags or ends of the wire may either be cut flush with the coils or extend beyond the spring axis as attachment points.
