    Keep these springs on hand so you can cut the right length whenever you need it. Bend their straight-cut ends into custom loops or hooks.
    Spring Steel—Strong and resilient, but best suited for dry environments since moisture will cause these springs to rust.
    Minimum Load—The amount of force required to start extending the spring.
    Spring Rate—To determine the spring rate of a cut spring, first multiply the spring rate given by the spring's original length, then divide the result by the cut length (in inches).
