These springs are made to help integrate components such as flanges, squares, hexes, rounds, bearing sets, gears, splines, bellcrank arms, threads and other machinable shapes into one piece. The springs also allow incorporation of consistent spring rates, precise payloads and multiple integral coils (multi-starts) that ordinary springs don't provide. They can be used as compression, extension, torsion, lateral translation and lateral bending springs, can be made out of machinable metals such as aluminum, stainless steel and titanium. They have no internal stresses to overcome before deflection occurs, since they can be configured to provide very precise, linear deflection rates with almost no residual stresses.
