The function of this spring is to react to a torsion moment around its longitudinal axis.
The ends of a torsion spring are attached to other components, and when those components rotate around the center of the spring, the spring tries to push them back to their original position.

Depending by final use, choices include straight torsion, straight offset, hinged, short hook ends, and hook ends. Torsion spring ends can be custom bent, twisted, hooked or looped to suit your project needs.
