Below is a list of Torsion Springs manufacturers from Southfield, Michigan. Torsion springs are a coil spring variety used to store rotational energy or to apply torque. Torque, in the simplest terms, is the measurement of rotational force. Unlike compression or extension springs, which are subject to compressive forces like squeezing, torsion springs are subject to rotational force (twisting) rather than linear force (pulling or pushing).
