What is Torsion Coil Spring

Coil springs or helical springs fall into four broad categories: compression springs, extension springs, torsion springs and spring guides. They are used in a wide range of applications, from tiny medical devices to automobiles to industrial equipment. Coil springs must be made to precise specifications in both size and material in order to perform properly, and at LML, we specialize in manufacturing custom coil springs for your most demanding applications.
