Custom torsion springs might have bends on the legs, one leg longer than the other, or pitch in between its coils when it is required to fulfill the function of a compression spring; to not only torque, but also compress. This makes your spring a custom torsional spring. These alterations and modifications to the spring’s dimensions are not manufactured on a stock torsion spring because stock springs may be used in many different devices or mechanisms. Custom springs are usually made to fulfill the requirements of a specific device or mechanism. You will also find custom torsion springs which don’t have bends on the legs, have equal leg lengths (typical legs), and don’t have any pitch in between the coils. This might happen when a customer has tight tolerances around the device so that a stock spring might not work. It is also the case when they are interested in ordering large torsion spring wholesale quantities.
